Achieving High-Performance Organic Long Persistent Luminescence Materials via Manipulation of Radical Cation Stability.

ABSTRACT: Organic long persistent luminescence (OLPL) materials, with their hour-long afterglow, hold great promise across numerous applications, yet their performance lags behind that of inorganic counterparts. A deeper understanding of the underlying photophysical mechanisms, particularly the effective control of radical intermediates, is essential for developing high-performance OLPL materials; while systematic studies on the intrinsic stability of radical intermediates and their impact on OLPL performance remain scarce. Here biphenyl groups is introduced into a luminophore-matrix-donor three-component OLPL system. By varying substituents at the ortho-position of the biphenyl groups, the stability of radical cations is systematically modulated, and their influence on OLPL properties is investigat
