Abstract

The photophysics of the two novel solitaire porphyrazines 3 and 4 (obtained via coordination of PdCl2 and PtCl2 to the peripheral bis(dimethylamino) entity of the Zn-porphyrazine 1, respectively) have been examined using absorption, emission and transient absorption spectroscopy. While the free ligand 1 exhibits neither fluorescence nor triplet absorption, the peripherally metallated derivatives 3 and 4 display both fluorescence as well as intersystem crossing.
