摘　　要：Three poly(2,5 dialkoxyl phenelene vinylene) derivatives were synthesized from 1,4 dialkoxyl benzene and 1,2 dibromoethane by Friedel Crafts reaction followed by dehydrogenation. Their molecular weights are determined by gel permeation chromotography and structures characterized by IR, 1H NMR and UV Vis spectroscopy . All of the polymers obtained are constructed through a great number of π conjugated bonds.Three poly(2,5 dialkoxyl phenelene vinylene) derivatives were synthesized from 1,4 dialkoxyl benzene and 1,2 dibromoethane by Friedel Crafts reaction followed by dehydrogenation.
