Remote Electrostatic Effect between Octahedral Ru/Ir‐Complexes and Aromatic Micelles to Improve Their Photofunctions in Water

Angewandte Chemie, EarlyView.
The aqueous‐state encapsulation of cationic Ru(II)/Ir(III)‐complexes is efficiently demonstrated by anionic aromatic micelles via remote electrostatic interactions. The resulting host–guest composites exhibit enhanced metal‐complex‐based emission (∼3 to 10‐fold) and NIR emission through guest‐to‐guest FRET upon co‐encapsulation.
