Abstract
The new monomer beta,beta-dibromo-4-ethynylstyrene was synthesized and polymerized by the Heck reaction to give a partially soluble, conjuga ted hyperbranched polymer. The polymer structure was elucidated using standard spectroscopic techniques and with the aid of model compound s ynthesis. Theoretical calculations using the AM1 method were carried o ut and they showed that conjugation in the polymer is partially disrup ted by twisting of the benzene rings. Both the model compound and the polymer showed luminescence. (C) 1996 Elsevier Science Ltd.
