摘要

Simple and efficient method of Suzuki polycondensation catalyzed by oxygen-stable Diaminocarbene Palladium(II) complexes is proposed. Compared to the conventional Suzuki polycondensation catalyzed by Pd(0) phosphine complexes

much lower catalyst loading is required to prepare polymers with high molecular weights and improved photophysical characteristics.

Abstract

An efficient

simple

and convenient method for Suzuki polycondensation using a diaminocarbene palladium(II) catalyst under aerobic conditions was developed. Reactions between aromatic diboronic acid bis(pinacol) ester and different aromatic dibromides

both with electron-donating and electron-withdrawing fragments in the structure

were carried out. Various reaction conditions

such as the effect of catalyst concentration and solvent

were investigated. The molecular weight characteristics

photo- and electroluminescence properties of the synthesized polymers were studied.
