โœฆ Synopsis

Facile synthesis of 1,2-phenylene-bridged porphyrin dimers via Pd-catalyzed cross-coupling reaction and their photophysical properties only moderately perturbed by inter-porphyrin electronic interactions are reported.

The synthesis of 4-amino-1,2,4-triazole linked porphyrin-chlorin dimer and porphyrin dimer is described. New cationic porphyrin dimers were synthesized via the alkylation of the nitrogen atoms of 4,4%-bipyridine and 1,2-di-(4-pyridyl)ethene by meso-monobromomethylporphyrin. These cationic bisporphyr
