Abstract
This work reports on the synthesis and photophysicochemical parameters of unsubstituted [Sb IIIPc] + I 3 - and octa-phenoxy ([Sb IIIOPPc] + I 3 - ) and -4- t-butylphenoxy ([Sb IIIOTBPPc] + I 3 - ) substituted antimony phthalocyanines. Photophysical and photochemical properties were studied for these complexes in dimethylsulfoxide, dimethylformamide and toluene. The excitation spectra of oxidized antimony (Sb(V)Pc) derivates were similar to absorption spectra. Low fluorescence quantum yields, high triplet quantum yields and low triplet lifetimes were observed as the result of heavy atom (antimony ion).
