摘      要：Comprehensive Summary Currently,solid-state fluorescent carbonized polymer dots(CPDs)have attracted attention increasingly due to their applications for optoelectronic ***,designing CPDs possessing solid-state fluorescence and clarifying the fluorescence mechanism remain ***,we initially synthesized a novel type of polythiophene derivatives CPDs,poly-4,4’-(thiophene-3,4-diyl)dibenzoic acid carbonized polymer dots(PDBA-CPDs)with solid-state ***,the structural and optical characterization revealed that the solid-state fluorescence originated from the aggregation induced emission of the *** brief,in aggregation state,the remaining polymer structure groups on the surface of the CPDs overlapped and weakened the non-radiative transition,enhancing solid-state fluorescence ***,three polythiophene-derived CPDs were designed to further demonstrate the aggregation induced solid-state fluorescence ***,owing to their unique properties of solid-state fluorescence,the white LEDs(light emitting diodes)were fabricated with high color rendering index(CRI)of 82.7 and CIE coordinates of(0.37,0.39)using commercial 460 nm chip.
