- Preparation and application of a D-A conjugated electrochromic flexible electrode with side chain carbazole active groups in supercapacitors
-
Electrochromic power storage devices (ESCs) integrate energy storage and electrochromic behaviour into a single full cell that can enable the visualization of the energy status by the naked eye. One challenge for achieving practical applications is the development of intelligent and portable all-organic electrochromic power storage devices. Donor-acceptor (D-A) polymers have been widely studied for their tunable electronic properties. However, studies of polymers with optoelectrochemical, electrochromic and electrochemical performance substituted with different carbazole groups have drawn little attention. Herein, we designed and synthesized four polymers with carbazole side chains. The polymer solutions can be simply processed into thin films. Meanwhile, they exhibit an obvious and reversible colour transition between red (uncharged state) and dark blue (charged state), with an optical contrast of 37.35% and a colouring efficiency of 241.40 cm2 C-1 at a wavelength of 661 nm. The electrochromic components of PI-2 and PI-3 were assembled and proved to be able to change colour in the bending state. Hence, the energy storage level of the ESCs is directly related to their colour and can be determined by the naked eye, which means that they can be incorporated with other energy cells to visually display their energy status. PI-3 was assembled into a flexible supercapacitor that lighted up a 1.5 V light-emitting diode. Finally, the results present significant potential of PI-3 electrodes for efficient energy storage and electrochromic properties with stable transmittance changes, demonstrating their potential as smart wearable energy storage devices. This work can provide a platform for developing smart and portable power storage devices with enhanced energy densities.

- Pd-Catalyzed Decarboxylative Ortho-Halogenation of Aryl Carboxylic Acids with Sodium Halide NaX Using Carboxyl as a Traceless Directing Group
-
A highly regioselective Pd-catalyzed carboxyl directed decarboxylative ortho-C-H halogenation of cheap o-nitrobenzoic acids with NaX (X = I, Br) under aerobic conditions has been established. The utility of the method has been demonstrated by the gram-scale reaction and derivatization of the product. Experimental results have confirmed Pd and Bi played critical roles in the transformation and indicated the transformation might proceed via 2-halo-6-nitrobenzoic acid derivative intermediate.

- Method for synthesizing m-iodonitrobenzene compound
-
Provided is a method for synthesizing m-iodonitrobenzene; in the presence of oxygen gas, a palladium catalyst, a copper additive, a bismuth reagent and potassium phosphate, an o-nitrobenzoic acid compound and metal iodide are subjected to a substitution reaction in an organic solvent to form a corresponding m-iodonitrobenzene compound, wherein a metal in the metal iodide is an alkali metal or an alkaline earth metal. The method has obvious advantages of cheap and easily obtained reaction raw materials (including o-nitrobenzoic acid and MI), small amount of the metal catalyst, minimum environmental pollution with oxygen gas as an oxidant, good tolerance on various functional groups on an aromatic ring and the like. The method can be widely applied in the fields of synthesis of drugs, materials, natural products and the like in industrial and academic circles.

- Iron(III) complexes with meta-substituted bis(arylimino)pyridine ligands: Catalyst precursors for the selective oligomerization of ethylene
-
Bis(arylimino)pyridine iron(III) complexes containing meta-halogen substituents at the iminophenyl rings were synthesized and characterized. In contrast to iron(II) complexes, the presence of at least one ortho-substituent at the iminophenyl rings is not obligative for catalytic activities of these iron(III) complexes. After activation with methylaluminoxane (MAO), these catalysts oligomerize ethylene to give also internal and branched olefins besides the expected linear α-olefins. The widths of the resulting molecular weight distributions and the degrees of isomerization of the resulting oligomers strongly depend on the substitution pattern at the ligand frameworks.

(Chemical Equation Presented) The inhibitor of type 1 17β- hydroxysteroid dehydrogenase EM-1745 (1) exhibits affinity for both the substrate (estrone or estradiol) and the cofactor (NAD(P)H) binding domains. However, to increase its bioavailability, this compound needs to be simplified. The efficient and convergent synthesis of simplified substrate/cofactor hybrid inhibitors (compounds 2) involving a cross-metathesis and a Sonogashira coupling reaction as key steps is described. Compounds 2a-c were also tested as enzyme inhibitors and compared to EM-1745.

- Syntheses and Spectral Properties of several Branched-chain Polyphenyls containing 1,2,3-Trisubstituted Ring(s)

Nine polyphenyls, including six new compound, 3'-phenyl-o-quaterphenyl (3), 2,6-diphenyl-m- (4), 2,6-diphenyl-p-terphenyl (5), 2,6,5'-triphenyl-m-terphenyl (6), 2',2''-diphenyl-m-quaterphenyl (8), and 2'-(phenyl-d5)-m-terphenyl (9), were synthesized by the Ullmann coupling reaction of aryl iodide(s) or by the Karash-type coupling reaction of deuterated aryl Grignard reagent with aryl iodide catalyzed by bis(acetylacetonato)-nickel(II).Infrared studies of the polyphenyls showed that the range 730-770 cm-1, generally accepted as the position of the C-H out-of-plane bending bands of phenyl rings, should be widened slightly to 730-781 cm-1.The high frequency bands were found to be correlated closely to the sterically overcrowded structure of terminal rings.Proton magnetic resonance spectral studies indicated that the characteristic spectral features of the polyphenyls containing 1,2,3-trisubstituted ring(s) were fully consistent with their conformational aspects deduced from stereomodels.Ultraviolet spectral data suggeted that the most probable conformation of the highly crowded 3',6''-diphenyl-o-quaterphenyl (1) is one in which the interplanar angles of the pivot bonds between the 1,2,3-trisubstituted ring and three benzene rings are rather smaller than those of the less crowded 2'-phenyl-m-terphenyl (2).Keywords - Ullmann reaction; nickel-complex-catalyzed cross-coupling; quaterphenyl; deuterated quaterphenyl; quinquephenyl; sexiphenyl; polyphenyl; IR; UV; 1H-NMR
