ChemInform Abstract

In the course of synthesis of title copolymer from fluorinated and nonfluorinated bissulfonium salt monomers, a decrease of both conversion and yield is observed as a more fluorinated monomer is used. An increasing fluorine content causes a significant decrease of intensity and, surprisingly, a very slight red shift in photoluminescence spectrum, a slight blue shift in electroluminescence spectra and a significant blue shift in UV and visible absorption spectra.
