Triplet and singlet energy transfer in carotene-porphyrin dyads: Role of the linkage bonds

Article abstract of DOI:10.1021/ja00036a002

A series of carotenoporphyrin dyad molecules in which the carotenoid is covalently linked to a tetraarylporphyrin at the ortho, meta, or para position of a meso aromatic ring has been prepared, and the molecules have been studied using steady-state and tr
