title: Improvement of (bipy)Pt(XR)2 (X=O, S) type photosensitizers by covalent dye attachment.
abstract: Irradiation into the dye-based absorption band of complexes ((t)Bu(2)bipy)Pt(SR)(2) and ((t)Bu(2)bipy)Pt(OR)(2) where R denotes a coumarine-based thiolate and alkoxolate substituent populates the same excited triplet state as is obtained by excitation into the much weaker (RX)(2)Pt→(t)Bu(2)bipy (X = O, S) charge-transfer band. This paves the way toward more efficient photosensitizers.
