摘要: Abstract A magnesium porphyrazine possessing isophthaloxybutylsulfanyl substituents in the periphery was synthesized and subjected to various photophysical studies, including optical absorption emission measurements. Moreover, synchronous fluorescence spectra were recorded a contour three-dimensional map of excitation-emission studied obtained. The macrocycle exhibited interesting solvatochromic effects many different solvents. Upon excitation with visible light, it generated singlet oxygen low quantum yield, therefore when encapsulated liposomes no photocytotoxicity in vitro study on human carcinoma LNCaP cell line.
