Abstract

Directly 2,12- and 2,8-linked Zn^II porphyrin oligomers were prepared from 2,12- and 2,8-diborylated Zn^II porphyrin by a cross platinum-induced coupling with a 2-borylated Zn^II 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 Zn^II porphyrin units for 2,12- and 2,8-linked Zn^II porphyrin arrays, respectively.
