A facile synthesis of 1,4-dialkoxy-2,5-diiodobenzenes: reaction of dialkoxybenzenes with iodine monochloride in alcoholic solvents

A facile synthesis of 1,4-dialkoxy-2,5-diiodobenzenes via diiodination of the corresponding dialkoxybenzenes with iodine monochloride has been developed. Employment of ah alcoholic solvent as a reaction medium is crucial for attaining a high yield; the reaction in a nonalcoholic solvent usually resulted in a poor yield. The diiodobenzene derivatives are useful intermediates in the synthesis of such advanced materiais as soluble phenylenevinylene polymers anal dialkoxy derivatives of 7,7,8,8-tetracyanoquinodimethane.

Triphenylamine and terpyridine-zinc(ii) complex based donor-acceptor soft hybrid as a visible light-driven hydrogen evolution photocatalyst

A donor-acceptor coordination polymer (TPA-Zn) was synthesized by Zn(ii)-assisted self-assembly of an in situ generated triphenylamine (TPA) cored tristerpyridine ligand. The polymer absorbs a broad-spectrum of light and exhibits visible light-assisted hydrogen generation (27.1 mmol g-1 over 9 h) from water with 2.9% quantum efficiency at 400 nm. The microscopy images show a mesoscale fibrous morphology and the Brunauer-Emmett-Teller (BET) analysis reveals the porous nature of TPA-Zn (surface area: 234.5 m2 g; d = 6.98 nm), both of which are helpful for substrate diffusion during catalysis.

Synthesis, optical and electrochemical properties of novel D-π-A type conjugated polymers based on benzo[c][1,2,5]selenadiazole unit via alkyne module

Three novel donor-π-acceptor (D-π-A) type conjugated polymers P-1, P-2, and P-3 based on benzo[c][1,2,5]selenadiazole moiety and phenyl or naphthyl group via alkyne module were firstly prepared by Sonogashira-Hagihara reaction of various diiodo aryl compounds with the key monomer 4,7-diethynylbenzo[c] [1,2,5]selenadiazole (M-1), which was synthesized by a strategy of firstly introducing the trimethylsilylacetylene flexible group, and then introducing the selenium atom. The polymers displayed obvious absorption peaks at the region from 503 to 510 nm and narrow orange-red or red fluorescence in the range of 576-595 nm because benzo[c][1,2,5]selenadiazole unit can effectively reduce the lowest unoccupied molecular orbital (LUMO) energy levels of these polymers. The band gaps of these polymers can be tuned in the range of 1.37-1.76 eV by using different aryl donor groups. These findings indicate that these benzo[c][1,2,5]selenadiazole-based conjugated polymers can be developed for excellent fluorescent materials.

A helical chiral polymer-based chromo-fluorescence and CD response sensor for selective detection of trivalent cations

A novel chiral (S)-BINAM-based fluorescent polymer sensor was designed and synthesized by the polymerization of 4,4′-((2,5-dibutoxy-1,4-phenylene) bis(ethyne-2,1-diyl))-dibenzaldehyde (M-1) with (S)-2,2′-binaphthyldiamine (S-BINAM, M-2) via Schiff's base formation. The resulting helical chiral polymer sensor exhibited remarkable turn-on bright blue fluorescence color upon the addition of trivalent metal ions under a commercially available UV lamp; this change can be clearly observed by the naked eye for direct visual discrimination at low concentration. More importantly, the addition of trivalent metal cations can lead to a most pronounced change of CD spectra of the chiral polymer indicating this kind chiral sensor can also be used as a sole probe for selective recognition of trivalent metal cations based on CD spectra.
