Abstract

A new low-symmetry tetraazaporphyrin has been synthesized and characterized by 1H NMR, electronic spectroscopies and high resolution mass spectrometry. The photophysical behavior of the newly synthesized low-symmetry zinc tetraazaporphyrin ZnPz 1 has been examined and compared with that of the symmetrical tert-octylphenoxy zinc phthalocyanine ZnPc 2, by using steady-state absorption and fluorescence, cyclic voltammetry, molecular orbital calculation, and femtosecond transient absorption techniques.
