Herein, a new synthetic access to poly(arylene-1,2-diarylvinylene) (PAV-DA) derivatives is presented by novel polyolefination of bifunctional N-tosylhydrazones using base-activated elemental sulfur. PAV-DAs are particularly interesting due their aggregation-induced emission (AIE) properties, resulting in high solid-state photoluminescence quantum yields. The procedure allows the successful synthesis eight homopolymers and two copolymers with different arylene backbones aryl side chains from easily accessible monomers, not requiring use expensive or highly hazardous materials. polymers obtained good yields number average molecular weights up 26.9 kDa. Thermal analysis reveals exceptionally thermal stability degradation temperatures as 541 °C glass transition 263 °C. Furthermore, it found that polymer properties adjustable via copolymerization.
