ABSTRACT:Starting from 1,2-naphthalocyanine lutetium acetate (1,2-NcLuOAc) the unsymmetrical lutetium phthalo(naphthalo)cyanine (1,2-NcLuPc) has been synthesized and characterized by optical absorption spectra and fast atom bombardment (FAB) mass spectrometry. 1,2-Naphthalocyanine shows several geometrical isomers, both the mixture (noted Nc AE ) and one of them (Nc C S ) have been used for forming the corresponding bismacrocycles. As a result the first racemic mixture of a chiral unsubstituted phthalo(naphthalo)cyanine complex has been synthesized and characterized.
