Abstract

The quenching of the photoluminescence of [Pt(binap)2] by oxygen has been studied. Generation of singlet oxygen was confirmed by NIR spectroscopy. The usefulness of the Pt complex as a photosensitizer was established using a singlet oxygen scavenger, 1,3-diphenylisobenzofuran (DBF). The mechanism for the generation of singlet oxygen is discussed.
