## Abstract Poly(1,4‐phenylenevinylene) and poly(1,4‐phenyleneethynylene) were prepared from __trans__‐1,2‐dibromoethylene and 1,4‐bis(2‐bromoethynyl)benzene respectively with aryldiboronic acids by a Suzuki cross‐coupling reaction. The polymers were synthesized in a two‐phase system at room temper
## Abstract Poly(2,5‐dipropargyloxy‐1,4‐phenylenevinylene) (PDPPV) and its copolymers were prepared as thin films via the organic‐soluble and water‐soluble precursor routes. Elimination and crosslinking reactions could be controlled by the temperature. Crosslinked PDPPV is stable up to 450°C. The c
