摘要

A novel conjugated polymer (PBBPTDEHP), which has a regioregular structure, was successfully synthesized in chloroform using FeCl3 as the oxidizing reagent. The polymer shows good thermal stability and can be easily dissolved in xylene, chloroform, tetrahydrofuran (THF) and other common organic solvents. Due to the symmetry of the monomer, the polymer formed contains no head-head conrgurational isomers and has high regioregular structure. The structure and the purity of the polymer were characterized by FTIR, 1H NMR, 13C NMR, MS, and elemental analysis. The absorption edge of the UV

摘要

Poly[1,4-bis(4-alkyl-2-thienyl)-2,5-disubstituted phenylene]s and their monomers have been regioselectively synthesized in high yield. The head-to-head defined structures of all polymers and monomers are demonstrated by FT-IR, 1H, 13C NMR and elemental analysis. All new materials exhibit good thermally stability, optical, electrochemical properties. Their HOMO and LUMO energy levels are determined by cyclic voltammetry and UV-vis measurement. The improvement of absolute PL quantum yields of all six polymers in the solid films have been approved after the aromatic groups were introduced into the main chain of polythiophene. Three materials were chosen to be fabricated as single layer LED devices.

摘要

The copolymers of oligothiophenes and 1,4-bis(1,3,4-oxadiazol-2-yl)-2,5-dialkoxybenzene were nthesized with blue, green and orange emissive light depending on the length of the oligothiophene.
