Energy and electron transfer processes in self-organized porphyrin and chlorin triadic and pentadic complexes

Self-organized arrays stable at room temperature containing three or five macrocyclic fragments have been constructed using two-fold ligation of Zn-porphyrin and Zn-chlorin chemical dimers by di- or tetrapyridyl substituted porphyrins, chlorins or tetrahydroporphyrins. Spectral, photophysical and thermodynamic properties of the ensembles have been studied in the temperature range from 140 to 360 K. Kinetic behavior of the complexes upon optical
