Synthesis of Porphyrin Cored Hyperbranched Polymers

Abstract

Reversible transesterification has been used to synthesize a porphyrin cored hyperbranched polymer. Fractionation, followed by UV and mass spectroscopic analysis, revealed that the porphyrin cored had been incorporated across the complete molecular weight range of the polymer and with a high degree of incorporation (approaching 100%). These fractionated samples therefore represent simple/crude analogues of porphyrin cored dendrimers.
