1,3,5,9-Tetra(4-(1,2,2-triphenylvinyl)phenyl)pyrene (TTPE(1,3,5,9)Py): a prominent blue AIEgen for highly efficient nondoped pure-blue OLEDs

Abstract

By integrating four tetraphenylethylene (TPE) groups into the pyrene ring at 1,3,5,9-positions, a highly twisted pyrene-based blue AIEgen has been developed for highly efficient nondoped pure-blue OLEDs.
