Synthesis, characterization and theoretical studies of novel phthalocyanine complexes

New class of metal-free and metallophthalocyanines (M=Zn, Cd) bearing 5,6-dihydro-1,4-dithiin-2,3-dithiole substituents peripheral positions were synthesized. The photochemical properties of these compounds were investigated and associated with aggregation type in each case. Theoretical calculations, using DFT, were also performed in order to investigate the possible identities of the new molecules. The effect of central metal on the planarity of Pc core was also examined.
