Spectral study of monoisothiocyanato-substituted 3:1 asymmetrical phthalocyanine zinc(II)]

Electronic absorption spectra of three monoisothiocyanato-substituted asymmetrical phthalocyanine zinc(II), 2-isothiocyanato-9,10,16,17,23,24-alkyloxyphthalocyanine zinc(II) (RO)6 (NCS)PcZn(II)] (R = n-C4H9, n-C5H11, n-C10H21), were measured in five organic solvents. The effect and order of the substitute groups and solvents were studied by electronic absorption spectra. The changes of lamda(max) data are very small between monoamino- and monoisothiocyanato-substituted asymmetrical phthalocyanines. The order of lamda(max), data is listed here, CHCl3>CH2Cl2>toluene in non-coordination solvents; DMF>THF in O-coordination solvents. The fluorescence spectra of these complexes were measured in organic solvents at the same time. The effect and order of the substitute groups, solvents and concentrations were studied on the maximum wavelength of emission and fluorescence intensity. The lamda(em,max) data of fluorescence emission are among 690-700 nm. The order of lamda(em,max) data is listed here, DMF>THF in O-coordination solvents and almost the same in non-coordination solvents. The fluorescence intensity is very strong in DMF and THF. The order of fluorescence intensity is listed here, DMF>THF in O-coordination solvents; toluene> CH2Clz > CHCl3 in non-coordination solvents. They have special fluorescent effect and should be expected to become a photosensitizer of photodynamic therapy in future.
