Popis:	The photophysical properties of thin films of Zn-monopyridyltriphenylporphyrin (Zn(4-Py)TrPP) obtained by the method of centrifugation on a quartz film substrate have been investigated. The results of the analysis of the measured excitation and luminescence spectra and also of the kinetic curves of fluorescence depolarization, as they decay, of the Zn(4-Py)TrPP films permit the conclusion that Zn-meso-monopyridylporphyrins self-organize into aggregates. The symmetric closed tetramer ([Zn(4-Py)TrPP]4) seems to be the most probable aggregate of Zn-meso-monopyridylporphyrins.
