The synthesis of the new phthalocyanine includes fluorine groups and investigation about photophysical and photochemical properties of the metalfree and zinc phthalocyanine

In this work, 4-(3-(trifluromethyl)benzilthio)phthalonitril (1) compound was synthesized using (3-(triflorometil)phenyl)metanthio and 4-nitrophthalonitrile as starting compounds. The metal-free phthalocyanine (2) was synthesized using dinitrile compound (1) with n-pentanol, DBU. Beside this, zinc (II) phthalocyanine (3), cobalt (II) phthalocyanine (4), iron (II) phthalocyanine (5) were synthesized using dinitrile compund (1) DMAE, DBU and dry Zn(CH3COO)2, CoCl2, Fe(CH3COO)2 salts, respectively. Also PDT properties of metal-free phthalocyanine (2) and zinc (II) phthalocyanine (3) were investigated. The structures of the synthesized original compounds were identified by using several spectral techniques, (IR, 1H- NMR, UV-vis ve MALDI-TOF-MS).
