Abstract

Directly 2,12- and 2,8-linked ZnII porphyrin oligomers were prepared from 2,12- and 2,8-diborylated ZnII porphyrin by a cross platinum-induced coupling with a 2-borylated ZnII porphyrin end unit followed by a triphenylphosphine (PPh3)-mediated reductive elimination. Comparative studies on the steady-state absorption and fluorescence spectra and the fluorescence lifetimes led to a conclusion that the exciton in the S1 state is delocalized over approximately four and two ZnII porphyrin units for 2,12- and 2,8-linked ZnII porphyrin arrays, respectively.
