Synthesis and properties of tetra-4-morpholinyl(piperidinyl)-5-R-substituted phthalocyanines
摘要:
Demetallation of magnesium tetra-4-morpholinyl(piperidinyl)-5-R-substituted phthalocyanines was performed to obtain the corresponding metal-free phthalocyanines. Their electronic absorption spectra were shown to depend on the nature of the solvent. It was found that both the saturated heterocycle and the oxyaryl substituent have almost no effect on the position of the absorption maximum.
