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. In addition, the photoluminescence properties of the diaroylbenzenes were dependent on the morphology and reversibly variable by thermal and solvent vapor stimuli.
