## Abstract Three alternating conjugated copolymers of cyanosubstituted poly(__p__βphenylene vinylene) (CNβPPV) with phenylene ethynylene and thienylene vinylene moieties, **P1, P2,** and **P3,** were synthesized via crossβcoupling polycondensation with Pd(PPh~3~)~2~Cl~2~ as a catalyst. Their struc
A new p-phenylene-vinylene-thiophene-based siloxane block copolymer has been synthesized. The copolymer consists of alternating rigid and flexible blocks. The rigid blocks are composed of phenylene-vinylene-thiophene-based units, and the flexible blocks are derived from 1,3-dialkyldisiloxane units.
