K. Susumu et al., SYNTHESIS AND PHOTOCHEMICAL PROPERTIES OF THE ORTHOGONAL PORPHYRIN TRIAD COMPOSED OF FREE-BASE AND PHOSPHORUS(V) PORPHYRINS, Chemistry Letters, (10), 1995, pp. 929-930
A novel triad molecule composed of three porphyrins was synthesized by
the use of the axial substitution of phosphorus(V) porphyrin. Photoch
emical properties of the triad suggest that the photoinduced electron
transfer was accomplished.
