摘要

A new bis(aroylacetylene) containing triazole and fluorene moieties is synthesized by click chemistry. Polycyclotrimerization of the monomer is catalyzed by piperidine in refluxed dioxane, furnishing a regioregular poly(aroylarylene) in a satisfactory yield. The hyperbranched structure of the polymer is characterized spectroscopically with satisfactory results. The polymer enjoys no metal detriment and is soluble in common organic solvents such as tetrahydrofuran (THF), chloroform, dichloromethane (DCM), and N,N-dimethylformamide (DMF).
