Abstract

Unsymmetrical zinc phthalocyanine (Pc) bearing one pyrene (Py) and six tert-butylphenoxy units was synthesized in 3 steps. The unsymmetric zinc phthalocyanine carrying the protecting group was synthesized in the first step. In the second stage, the protecting group was removed and in the final stage pyrene structure was introduced under the condition of the Sonagashira coupling reaction. The new compound was characterized by using spectroscopic techniques. The photophysical measurements of the conjugated structure were performed to determine the effect of the pyrene group on the fluorescence of Pc. It was determined that the absorption of the pyrene structure around 350 nm was overlapping with the B-band of phthalocyanine after conjugation. Fluorescence quantum yield and lifetime were calculated. The fluorescence quenching examinations were performed by adding the different concentration of benzoquinone in DMF and the Ksv and kq values of unsymmetrical zinc phthalocyanine (5) were determined.
