Abstract

Abstract A new molecular design of organic emitters exhibiting efficient solid-state fluorescence, which involves planarity breaking of N, N-diorganoquinacridones, is presented. The new design principle led to the development of dimethyl 2, 5- diaminoterephthalates and 2, 5-diamino-1, 4-diaroylbenzenes, which emitted green to yellow and yellow to red light with high-to-excellent quantum yields, respectively.
