Hyperbranched aromatic polymers were prepared by Friedel-Crafts reaction wi
th Lewis acid, AlCl3 and ZnCl2, as the catalysts. In this work, hyperbranch
ed polybenzyl (PB) and poly(methylene)naphthalene (PN) were synthesized and
characterized by H-1-NMR and GPC. In addition, their florescence propertie
s were measured with steady-state florescence spectra in THF and ethylene d
ichloride. The quantum yields of polybenzyl and poly(methylene)naphthalene
in ethylene dichloride are much larger than those in THE.
