Abstract

Tetraazaporphyrin phosphorus(V) complexes with electron-rich nitrogen and sulfur atoms at the peripheral positions were synthesized and characterized. The absorption spectra show a broad, intense band between the Soret and Q bands, which can be assigned to n → π∗ bands from the electron-rich heteroatoms to the electron deficient macrocyclic TAP core. Their detailed optical properties were also investigated by magnetic circular dichroism spectroscopy.
