✦ Synopsis

New types of self-organized porphyrin arrays were constructed. The systems contain dimeric TT and trimeric tartrates TTT connected with 1,6-hexamethylendiol spacers and the trench porphyrin P bridged with 2,4-dinitro-isophthalic acid. The 17 -P and TTT -P systems exhibit unique exciton splitting bands at 437 mn and 440 nm upon allowing the temperature of the samples to lower, of which splinting energies are 507 cm -I and 691 cm "1 respectively. The observed splitting of the Sorer bands strongly indicates the formation of porphyrin arrays on the tartarate templates.
