Abstract
AbstractThe metal complexes of a pivotal representative of the so‐called porphyrin‐phthalocyanine hybrid series ‐ 5,15‐diaryl‐10,20‐diazatetrabenzoporphyrin (Ar2TBDAP), ‐ recently made available by a new selective and versatile procedure, with Zn, Ni, Cu, and Pd were synthesized and characterized by single crystal X‐ray analysis, UV‐vis/NIR absorption and emission spectroscopy, nanosecond and microsecond time‐resolved (NSTA and TCSPC) experiments and by means of cyclic voltammetry. The complexes obtained are compared with the related tetrabenzo‐annelated tetrapyrrolic systems, including tetrabenzoporphyrin, phthalocyanine, and other hybrids, using both experimental data and the results of quantum chemical DFT and TD‐DFT computations. The Ar2TBDAP system reported shares sharp hyperchromic long‐wavelength absorption of phthalocyanines with the essential features of extended porphyrins including the possibilities of effective chemical modification through meso‐aryl substituents.
