Wang, Zian; Yao, Jingwen; Zhan, Lisi; Gong, Shaolong; Ma, Dongge; Yang, Chuluo published the artcile< Purine-based thermally activated delayed fluorescence emitters for efficient organic light-emitting diodes>, SDS of cas: 2382-10-7, the main research area is purine derivative thermally activated delayed fluorescence organic LED; diode light emitting organic purine derivative thermal delayed fluorescence; electroluminescent device organic purine derivative thermally activated delayed fluorescence.
Two thermally-activated delayed fluorescence (TADF) emitters (1PXZP and 2PXZP) based on a novel biol. base acceptor of 9-methylpurine and commonly used donor of phenoxazine (PXZ) were synthesized and characterized. Both target compounds possess nearly orthogonal configurations to reduce singlet-triplet splitting energy (ΔEST) for remarkable TADF character. The 2 emitters show good luminescence quantum yields (PLQYs), and the organic LEDs employing 1PXZP and 2PXZP as emitters display good performance with maximum external quantum efficiencies of 10.6 and 13.8%, resp. The efficiencies of 1PXZP based device show nearly no roll-off at 100 cd m-2 luminance due to the short delayed lifetime (τd) of 3.2μs. This work manifests that the biol. base is a promising acceptor for designing TADF materials.
