[Pt(tbtrpy)X]Y complexes (tbtrpy = 4,4',4"-(BU3)-B-t-2,2';6',2"-terpyridine) exhibit charge-transfer absorption bands that can be drastically red-shifted to long-wavelength visible absorptions with arylthiolates as X. Further extension to the near-IR (NIR) region is achieved with 7,7,8,8-tetracyanoquinodimethane (TCNQ(-)) as Y-, resulting in black absorbers with continuous UV-vis-NIR absorptions and opening up potential applications in energy research.
