- The effect of pore size and layer number of metal-porphyrin coordination nanosheets on sensing DNA
-
Metal-organic framework (MOF) nanosheets are a new type of two-dimensional nanomaterial. Their properties and performances are expected to correlate strongly with the sheet structure, particularly the number of layers (sheet thickness). Yet, synthetically controlling the layer number at the molecular scale is highly difficult. Herein, a facile method is introduced to fabricate substrate-supported MOF nanosheets with precisely controllable layer numbers, using the Langmuir-Blodgett technique. Large-area, porous, and uniform MOF nanosheets, based on 5,10,15,20-tetrakis[4′-(terpyridinyl)phenyl]porphyrin-cobalt(ii) (Co-TTPP) coordination polymer, were constructed and characterized in detail by atomic force microscopy, transmission electron microscopy, energy dispersive spectroscopy, powder X-ray diffraction, X-ray photoelectron spectroscopy, and a photoelectronic conversion technique. As a prototype sensor device, a series of substrate-supported Co-TTPP nanosheets was further investigated for the fluorescence detection of DNA towards rapid clinical diagnosis. The ten-layer Co-TTPP nanosheet exhibits an impressive performance with a very low detection limit of ca. 0.1 nM, outstanding specificity, and multiplexed DNA detection, comparable to some top-notch free-standing nanomaterial sensors. Importantly, our results also revealed the synergistic contributions of suitable pore size and optimal layer number of the Co-TTPP nanosheet for highly efficient DNA detection for the first time.

- Free radical oxidation reaction for selectively solvatochromic sensors with dynamic sensing ability
-
A novel BODIPY (boradiazaindacene) dye denoted as BODIPY-DT containing terpyridine unit has been designed and characterized. The dye is found to be selective and visual solvatochromic sensor toward DMF among test organic solvents. The sensing process displays time-controllable, dynamic signal outputs in the emission colors including red, purple, yellow and even white emission colors. It is presented that selective free radical oxidation reaction happens during the recognition process.

- Terpyridinebenzaldehyde isomers: One-pot facile synthesis
-
We have explored the use of (diethoxymethyl)benzaldehyde readily available as a starting material allowing us to end up with Terpyridinebenzaldehyde isomers. An environmentally friendly procedure was undertaken for the synthesis of a series of 4, 3 and 2-([2,2′:6′,2″-terpyridin]-4′-yl)benzaldehyde isomers (para, meta and ortho position). These compounds have been synthesized in one-pot conditions using ethanol and aqueous ammonia as solvents, at room temperature. This methodology offers substantial advantages with respect to its simplicity of operation, reaction time, satisfying yield of products and easy work-up procedure under mild reaction conditions. Apart from spectroscopic characterization, the structure of one of the Terpyridinebenzaldehyde derivative is confirmed by single-crystal X-ray diffraction.

- The synthesis of 4′-aryl substituted terpyridines by Suzuki cross-coupling reactions: Substituent effects on ligand fluorescence
-
Several 4′-aryl-substituted 2,2′:6′,2″-terpyridines (tpy-C6H4R) have been prepared by palladium-catalysed cross-coupling of 4′-bromoterpyridine or 4′-triflate-terpyridine (triflate = trifluoromethylsulfonyloxy) with aryl boronic acids or esters, RC6H4B(OR′)2 (R = H, m-NH2, p-CHO, -NO2, -CN, -NMe2, -NPh2). The new ligand 4′-mesityl-terpyridine (mesityl = 2,4,6-trimethylphenyl) was prepared in the same way. Similarly, 4′-bromophenylterpyridine (tpy-φ-Br) has been cross-coupled with aryl halides to generate several new biaryl-substituted terpyridines (tpy-φ-C6H4R where R = H, p-CN, NMe2, NPh2), together with two related compounds with pendent 3- or 4-pyridyl groups (tpy-φ-C6H4-py). For selected compounds, the alternative coupling strategy of reaction of a terpyridine-4-boronate or terpyridine-4-phenylboronate with the appropriate aryl halide has also been investigated (e.g. to prepare tpy-φ-C6H4NO2), but was generally found to be less satisfactory. All of the compounds are fluorescent in the UV region of the spectrum, the biaryl-substituted compounds being only slightly red-shifted compared to the monoaryl systems, but with the further red-shift that accompanies protonation being more significant for the former. Fluorescence lifetimes in solution are in the range 1-5 ns. The emission spectra of the aminobiphenyl-substituted compounds (tpy-φ-C6H4NR″2, where R″ = Me or Ph) display a large red-shift with increasing solvent polarity, suggesting the involvement of an intramolecular charge transfer state, as found previously for the two analogues omitting the phenyl ring (tpy-C6H4NR″2). In contrast to the latter, however, protonation or binding of a Lewis acidic metal ion to the aminobiphenyl compounds serves to quench almost completely their emission.
