Poly(phenylacetylenes) with short chlorinated ethylene oxide pendants: Synthesis, characterization and self-assembling

Two short chains of C₂H₄O_n hydrocarbons terminated with Cl atom were introduced into phenylacetylene and their polymerizations were described using organorhodium complexes as catalysts. The self-assembly of the polymers was analyzed as well as their application for controlling carbazole crystal growth. Phenylacetylene with pendant groups was successfully polymerized in high yields with high molecular weight by organorhodium catalysts. The polymers showed better thermal stability than the parent polyphenyl acetates.
