- Nitrogen-functionalised carbon nanotubes as a novel adsorbent for the removal of Cu(ii) from aqueous solution
-
This study investigated the introduction of 4′-(4-hydroxyphenyl)-2,2′:6′,2″-terpyridine (HO-Phttpy) onto the surface of multiwalled carbon nanotubes (MWCNTs) to obtain nitrogen-functionalized MWCNTs (MWCNT-ttpy). This novel material was characterised and tested for its possible use in the remediation of wastewater contaminated with heavy metal ions. Its efficacy was compared with that of acid-functionalized MWCNTs (MWCNT-COOH) for the removal of the heavy metal ion Cu2+ through adsorption. HO-Phttpy was first synthesized, followed by the functionalization of MWCNT-COOH to afford MWCNT-ttpy. MWCNT-ttpy showed significant textural enhancement due to an increase in the extent of functionalization. This was demonstrated by an increase in the surface area and pore volume of MWCNT-ttpy, from 126.8 to 189.2 m2 g-1 and 0.692 to 1.252 cm3 g-1, respectively, relative to MWCNT-COOH. Its application for Cu2+ removal showed a marked increase in uptake (qe), i.e. 19.44 to 31.65 mg g-1, compared with MWCNT-COOH. This is attributed to the introduction of more active/chelating sites for adsorption. Adsorption experiments were conducted at pH 5 at which equilibrium was reached after 360 min. The results showed that the adsorption process was best described by the pseudo-second order model. Among the isotherms tested, the Langmuir isotherm provided the best fit for the equilibrium data. Thermodynamic studies revealed that the adsorption process was spontaneous and endothermic. Desorption studies demonstrated a better removal efficiency of Cu2+ from MWCNT-ttpy, indicating its possible regeneration and the recovery of the Cu2+ adsorbate for reuse. Thus, MWCNT-ttpy shows superior properties for wastewater remediation compared to MWCNT-COOH.

- Visual recognition of melamine in milk via selective metallo-hydrogel formation
-
A series of novel six-coordinated terpyridine zinc complexes, containing ammonium salts and thymine fragment at the two terminals, have been designed and synthesized, which can function as highly sensitive visualized sensors for melamine detection via selective metallo-hydrogel formation. After fully characterization by various techniques, the complementary triple-hydrogen-bonding between the thymine fragment and melamine, as well as π-π stacking interactions may be responsible for the selective metallo-hydrogel formation. In light of the possible interference aroused by milk ingredients (proteins, peptides and amino acids) and legal/illegal additives (urine, sugars and vitamins), a series of control experiments are therefore involved. To our delight, this visual recognition is highly selective, no gelation was observed with the selected milk ingredients or additives. Remarkably, this new developed protocol enables convenient and highly selective visual recognition of melamine at a concentration as low as 10 ppm in raw milk without any tedious pretreatment.

- Synthesis, DNA binding, topoisomerase I inhibition and antiproliferation activities of three new binuclear terpyridine platinum(II) complexes
-
Three binuclear platinum(II) complexes, 1 ([Pt2(L)Cl2]Cl2), 2 ([Pt2(L)Br2]Br2) and 3 ([Pt2(L)I2]I2) (where L = 1,4-bi-[4′-(4-Hydroxyphenyl)-2,2′,6′,2″-terpyridine] butane) were synthesized and characterized by nuclear magnetic resonance, elemental analysis and mass spectrometry. The crystal structure of the new ligand L was determined by single crystal X-ray crystallography, and π–π stacking interactions were revealed in the geometry. Interactions of complexes with calf thymus DNA have been investigated by UV–Vis spectroscopy and fluorescence spectroscopy. Due to the structural differences, binuclear complex 3 exhibited higher binding affinity for calf thymus DNA with a DNA-binding constant Kb of 8.72 × 106 M?1. The competitive study indicated that the ethidium bromide (EB) can displaced by complexes 1–3 from the DNA-EB conjugation. The concentration-dependence unwinding of supercoiled circular plasmid pBR322 DNA by complexes 1–3 was observed via agarose gel electrophoresis. Meanwhile, complexes displayed obvious activities for inhibition of topoisomerase I. Herein the halogen leaving groups Cl?/Br?/I? presented in 1–3 showed significant effect on DNA binding and topoisomerase I inhibition activities. An evaluation of in vitro cytotoxicity for three complexes was performed by MTT assay in two cancer cell lines and normal cells as the control, respectively.

- Molecular engineering of head-tail terpyridine-Fe(II) coordination polymers employing alkyl chain linkers toward enhanced electrochromic performance
-
For the first time, we demonstrated that employing long alkyl chains as a nonconjugated linker in ditopic ligands is a promising strategy to construct Fe(II) coordination polymers for efficient electrochromics. Three new Fe(II) coordination polymers with ditopic organic ligands, in which two terpyridine moieties were connected by nonconjugated alkylchain linkers were synthesized. The morphology and hydrophobicity of the thin film made from the Fe(II) coordination polymers can be adjusted by changing the length of alkylchain linker. Benefiting from the longer length of the linker, the ditopic terpyridine-Fe coordination polymer FeL2 performed superior electrochromic performance as compared to FeL1 in the same condition, including shorter switch time, lower operation potential, higher optical contrast and coloration efficiency. Remarkably, the elaborate coordination polymer FeL2 exhibited the highest optical contrast up to 76% among the reported electrochromic materials based on Fe-complexes up to date. Due to the hydrophobic property of FeL3 probably benefit from its longer alkyl chain linkers, we carried out the electrochromic switch based on ionic Fe(II) coordination polymers using aqueous electrolyte for the first time.

- Anchoring of a terpyridine-based Mo(VI) complex on manganese ferrite as a recoverable catalyst for epoxidation of olefins under solvent-free conditions
-
A magnetically separable heterogeneous nanocatalyst was obtained by anchoring a terpyridine-based Mo(VI) complex on modified MnFe2O4 nanoparticles and characterized by Fourier transform infrared (FT-IR), X-ray diffraction (XRD) and diffuse reflectance spectroscopies (DRS), transmission electron microscopy (TEM), scanning electron microscopy (SEM), vibrating sample magnetometry (VSM), X-ray photoelectron spectroscopy (XPS) and Brunauer-Emmett-Teller (BET) analysis. The catalytic activity of the supported molybdenum based catalyst was evaluated in the selective epoxidation of various olefins (cyclooctene, limonene, 1-dodecane, 1-heptene, styrene, 1-indene, α-pinene, cyclohexene) with tert-butyl hydroperoxide (TBHP) as an oxidant under solvent-free conditions. This nanocatalyst was easily separated by using an external magnetic field and reused consecutively at least five times with no significant loss in selectivity and catalytic activity. The short reaction time, simple preparation, high conversion, good physicochemical stability and magnetic recycling of the catalysts are beneficial.

- Full-color emission of a Eu3+-based mesoporous hybrid material modulated by Zn2+ ions: Emission color changes for Zn2+ sensing: Via an ion exchange approach
-
We reported on the fabrication of a multicolor fluorescent sensor for Zn2+ ions based on the Eu complex functionalized mesoporous hybrid material Eu(TTA-MSN)2L (TTA: 2-thenoyltrifluoroacetone, HL: 4′-(4-carboxy-methyleneoxyphenyl)-2,2′:6′,2′′-terpyridinel). The material was characterized by Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, and N2 adsorption measurements. The results revealed that the material preserves mesoscopically ordered structures and exhibited highly uniform pore size distributions. Spectroscopic analyses showed that the mesoporous hybrid material Eu(TTA-MSN)2L exhibited the characteristic emission of Eu3+ ions, reasonably long lifetimes (0.62 ms), and high quantum yields (18.4%). Moreover, the material displayed a highly selective and sensitive function toward Zn2+ ions in aqueous solutions. This sensing function could be attributed to the cation exchange of Eu3+ in the parent material Eu(TTA-MSN)2L with Zn2+. More importantly, by only modulating the concentration of Zn2+ ions in the water solution of Eu(TTA-MSN)2L, a tunable full-color emission (including white-light emission) can be generated under single-wavelength excitation. To our knowledge, this effort is the first example of a multicolor emissive sensor for Zn2+ ions in water solutions based on lanthanide mesoporous hybrid material.

A suitable approach to stabilize palladium nanoparticles (Pd NPs), with an average diameter of 3–4 nm, on magnetic polymer is described. A new magnetic polymer containing 4′-(4-hydroxyphenyl)-2,2′:6′,2″-terpyridine (HPTPy) ligand was prepared by the polymerization of itaconic acid (ITC) as a monomer and trimethylolpropane triacrylate (TMPTA) as a cross-linker and fully characterized. Pd NPs embedded on the magnetic polymer were successfully applied in Suzuki–Miyaura and Mizoroki–Heck coupling reactions under low palladium loading conditions, and provided the corresponding products with excellent yields (up to 98%) and high catalytic activities (TOF up to 257 hr?1). Also, the catalyst can be easily separated and reused for at least consecutive five times with a small drop in catalytic activity.

- Controlled Formation of a Main Chain Supramolecular Polymer Based on Metal–Ligand Interactions and a Thiol-Ene Click Reaction
-
Supramolecular polymers with multiple functionalities and hierarchical structures have received considerable attention and become a hot research topic over the past years. Herein, a main-chain supramolecular polymer has been successfully fabricated by using metal–ligand interactions and a thiol-ene click reaction. 1H NMR, UV/Vis, DOSY, and viscosity measurements were carried out to investigate the molecular recognition and the process of supramolecular polymerization. From the study, the orthogonality between thiol-ene click reactions and the terpyridine–metal ions complexation behavior was testified, and supramolecular polymeric assemblies could be constructed by a one pot method. In the meantime, due to the incorporation of metal-ligand interactions, the supramolecular polymer shows stimuli-responsive properties toward chemical stimuli. Hence, this work could provide a methodology for developing supramolecular polymers as smart materials.

A new nanocatalyst was synthesized by immobilization of 4′-(4-hydroxyphenyl)-2,2′:6′,2″-terpyridine/CuI complex on ferromagnetic nanoparticles through a surface modification (FMNPs@SiO2-TPy-Cu). This heterogeneous catalyst was characterized using various techniques including Fourier transform infrared and energy-dispersive X-ray spectroscopies, transmission and scanning electron microscopies, X-ray diffraction, vibrating sample magnetometry and thermogravimetric analysis. The resulting nanocatalyst presented excellent catalytic activity for the regioselective syntheses of 1,4-disubstituted 1,2,3-triazoles and thioethers. The thermally and chemically stable, benign and economical catalyst was easily recovered using an external magnet and reused in at least five successive runs without an appreciable loss of activity.

- Attachment of chelating ligand pockets to tinorganyl moieties

Several approaches have been undertaken to realize the synthesis of a new tinorganyl compound with a 2,2′,6′,2″-terpyridine moiety. A synthesis pathway consisting of five steps with an overall yield of 51% was successful in producing Ph3Sn(CH2)3OPhttpy [HOttpy = 2,6-bis(2′-pyridyl)-4′-(p-hydroxyphenyl)pyridine], and insight has been gained into (partial) halogenation reactions with this unprecedented tinorganyl compound. Halogenation with hydroiodic acid produced a new dinuclear complex cation that resulted from head-to-tail coordination of two monocations. Furthermore, synthesis and yields of already known intermediates have been optimized. The products were analyzed and identified by 119Sn NMR, 1H NMR, and 13C NMR spectroscopy and ESI mass spectrometry, as well as by means of single-crystal X-ray diffraction. A new compound Ph3SnR, comprising a 2,2′,6′,2″- terpyridine-functionalized ligand R, has been synthesized in a five-step procedure. On attempting to halogenate this compound, a partially iodinated derivative was obtained that forms a head-to-tail connected dimer in the salt [(PhISn(CH2)3OPhttpy)2](I3) 2 with the terpyridine units acting as chelating ligands.
