Near-Infrared Emission from Bis-Pt~(II) Complexes of Doubly N-Confused Calix[6]phyrins(1.1.1.1.1.1)

摘要

Platinum(II) porphyrins display intense room-temperature phosphorescence with significantly shorter lifetimes than other types of phosphorescent organic compounds, which defies the fluorescence-phosphorescence distinction and makes them useful for such applications as oxygen sensing based on phosphorescence quenching and light-emitting devices (LEDs). For potential use in biological systems, however, the light-emitting Pt~(II) complexes should be designed to cover the full visible and near-infrared range (i.e., 650-1100 nm).
