Persistent electron-transfer state of a π-complex of acridinium ion inserted between porphyrin rings of cofacial bisporphyrins

Tanaka, Makiko,Ohkubo, Kei,Gros, Claude P.,Guilard, Roger,Fukuzumi, Shunichi

, p. 14625 - 14633 (2008/02/03)

A free-base cofacial bisporphyrin, H4DPOx, forms a π-complex with acridinium ion (AcH+) by π-π interaction in benzonitrile (PhCN). Formation of the H4DPOx-AcH+ π-complex was probed by UV-vis and NMR spectroscopy
