Abstract

Free base porphyrin-cored arylether dendrimers 2a~2c with terminal hydroxy groups in the periphery have been successfully prepared by hydroboration-oxidation reaction of corresponding 1a~1c with terminal vinyl groups in the periphery. Their zinc derivatives Zn-2a~Zn-2c have also been prepared. Absorption and fluorescence properties of 2a~2c and Zn-2a~Zn-2c with peripheral hydroxy groups were affected more by dendritic environments than 1a~1c and Zn- 1a~Zn-1c with peripheral vinyl groups.

Keywords: Arylether dendrimer, porphyrin, hydroxy group, absorption spectra, fluorescence spectra.
