Room-Temperature Phosphorescence of a Supercooled Liquid: Kinetic Stabilization by Desymmetrization

Preserved Fulltext
Metal-free single component liquid, developed by desymmetrizing C2-symmetrical diketone, exhibits room-temperature phosphorescence (RTP) and phosphorescent thermochromism in air. The unsymmetrical flexible core with as many as eight conformers kinetically stabilizes the supercooled liquid state. The RTP is unique the liquid that benefits from external heavy atom effect and suppresses oxygen diffusion, while produces an emissive conformer.
