Abstract

Abstract : Front Cover : Random and order‐controlled blue‐emitting polysiloxanes with thermally activated delayed fluorescence characteristics are successfully designed and synthesized as demonstrated by Zhongjie Ren, Shouke Yan, and co‐authors in article 2200064 . All of them display short prompt and delay fluorescence lifetimes and a very fast reverse intersystem crossing (RISC) rate of 10 7 s –1 . Compared with random copolysiloxanes, acceptors are well separated by donors for order‐controlled ones, which exhibit the faster RISC processes and the higher photoluminescence quantum yield.
