A class of cis-polyarylenevinylene: preparation and optical properties of the oligomeric polyarylenevinylene derivative having an 1,2-diphenylmaleimide moiety

A novel pi -conjugated polymer, poly(3,4-bisphenyl-N-n-hexyl-pyrrole-2,5-di one), was synthesized by dehalogenation polycondensation with the zerovalen t nickel complexes (the Yamamoto method), of which the chemical architectur e was based on the polyarylenevinylene having a fixed cis-vinylene group. T his polymer showed high solubility in common organic solvents, high spin-ca stability and high thermal stability up to ca. 400 degreesC and the T-g of 152 degreesC. The dilute polymer solution (THF) showed the greenish yellow photoluminescence with the maximum at 526 nm. (C) 2001 Published by Elsevie r Science Ltd.
