Alternative selection rules for one- and two-photon transitions in tribenzotetraazachlorin: Quasi-centrosymmetrical π-conjugation pathway of formally non-centrosymmetrical molecule

We compare the two-photon absorption (2PA) spectra of non-centrosymmetrical metal-free tribenzo-tetraazachlorin (H(2)TBTAC) and analogous symmetrical tetra-tert-butyl-phthalocyanine (H(2)TtBuPc). Surprisingly, despite formal lack of center of inversion, the 2PA spectrum of H(2)TBTAC displays a two-p...
