In this paper, we synthesize hyperbranched-triphenylamine polymer by electrophilic substitution reaction of methylene-triphenylamine cation. We use different method to synthesize methylene-triphenylamine cation, and discuss the influence on polymerization.We also synthesize isopropyl triphenylamine polymery isopropyl triphenylamine cation. The photophysical and thermo properties of these polymers have been explored.
