Abstract

Some specific organic dopants have been found to form intermolecular charge transfer complexes with phosphorescence-inactive organic matrices to mediate intersystem crossing of the organic matrices and thus activate room-temperature phosphorescence of the organic matrices. This method of boosting intersystem crossing paves the way for high-performance organic room-temperature phosphorescent materials.
