摘要：

The measurement of the electronic spectrum of triple-decker phthalocyanine trimer in solution showing the existence of low-lying excited states in the near-IR region is reported. The spectroscopic measurement in solution was made possible by using a newly synthesized trimer ([(Pc)Lu(CRPc)Lu(Pc)]:Pc=phthalocyanine; CRPc=15-crown-5 substituted Pc) having high solubility and purifiability. The lowest excited states caused by intra- and inter-macrocyclic HOMO-LUMO transitions are studied in terms of exciton coupling and charge resonance. The inherent differences between the trimer and dimer are elucidated. The assignment of absorption bands below 20 X 10(3) cm(-1) is discussed.
