Abstract

Abstract : Crystallization‐Enhanced Stability to Suppress Photooxidation Defect In article number 2200194, He Zhang, Sha‐Sha Wang, Ling‐Hai Xie, and co‐workers propose crystallization strategy of "molecular packing wall" to suppress the oxygen diffusion and eliminate the photooxidation defect of fluorene‐based wide‐bandgap semiconductors. Under UV‐irradiation, the crystalline film affords an ultrastable deep‐blue emission without the formation of g‐band (530 nm) presented in amorphous film.
