Covalently Linked Rotaxane Encapsulation of a Benzil Core for Consistent Organic Room-Temperature Phosphorescence Across Diverse Solvents

Abstract

We achieved room-temperature phosphorescence (RTP) of benzil, an aromatic diketone, in diverse solvents, as well as in amorphous solid states, by encapsulating the core with covalently linked cyclodextrins and introducing bulky capping moieties to effectively suppress intramolecular motions.
