Efficient room-temperature phosphorescence of covalent organic frameworks through covalent halogen doping

Room-temperature phosphorescence in organic solids is rare. In a recent article from Perepichka group E. Hamzehpoor, C. Ruchlin and coworkers reported highly phosphorescent boroxine Covalent Organic Frameworks (COFs) using the covalent doping approach and controlling the ratio of halogenated precursors. Their well-defined porosity enables oxygen sensing with millisecond response time over a wide range (10³…10^-5 torr) of partial oxygen pressure. Read the full paper in Nature Chemistry.
