New star-shaped poly:ene cpds. and poly:ene polymers, prepn. and use - useful as electroconductor and in optical and opto-electronic field, with 3 poly:ene chains attached to aromatic or hetero-aromatic ring system.

摘要

New star-shaped polyenes are of formula (I): A = 6-30C aromatic ring system or heteroaromatic ring system contg. N, O or S as hetero-atom; R1-3 = polyenes with 2-50 double bonds. New polymeric star-shaped polyenes (II) obtd. by crosslinking some (I), and the prepn. (I) and (II) are also claimed. USE/ADVANTAGE - (I) and (II) are used as electroconductive materials (claimed). (I) are soluble and their substits. can have definite orientation, making them of particular interest in the optical and optoelectronics fields. They are suitable for incorporation in high mol. systems with definite structure.
