Recently I am researching about LIGHT-EMITTING-DIODES; BIPOLAR HOST MATERIALS; HIGH-PERFORMANCE RED; HIGHLY EFFICIENT; PHOSPHORESCENT; BLUE; TRIPHENYLAMINE; ACCEPTOR; GREEN; ELECTRON, Saw an article supported by the National Nature Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [21790361]. Published in ELSEVIER SCI LTD in OXFORD ,Authors: Jin, MM; Chen, Y; Song, WX; Lian, H; Guo, HE; Dong, QC; Huang, JH; Su, JH. The CAS is 61-82-5. Through research, I have a further understanding and discovery of 1H-1,2,4-Triazol-5-amine. Product Details of 61-82-5
In this work, seven small molecular compounds named N,N-diphenyl-4-(2-phenylpyrimido [1,2-b]indazol-4-yl) aniline (1), N,N-diphenyl-4-(5-phenylpyrazolo [1,5-a]pyrimidin-7-yl)aniline (2), N,N-diphenyl-4-(5-phenyl[1,2,4]triazolo [1,5-a]pyrimidin-7-yl)aniline (3), 4,4′-(pyrimido [1,2-b]indazole-2,4-diyl)bis (N,N-diphenylaniline) (4), 4,4′-(pyrazolo [1,5-a]pyrimidine-5,7-diyl)bis (N,N-diphenylaniline) (5), 4,4′-([1,2,4]triazolo [1,5-a] pyrimidine-5,7-diyl)bis (N,N-diphenylaniline) (6), N,N-diphenyl-4-(4-phenylpyrimido [1,2-b]indazol-2-yl)aniline (7) with donor-acceptor (D-A) structure were designed and synthesized by employing triphenylamine (TPA) as donor and indazole, pyrazole and/or triazole as acceptor. Systematic study and analysis on thermal, photo physical, electrochemical properties of all compounds were performed. All compounds exhibit good thermal and morphological stabilities with decomposition temperatures (T-d) range from 270 to 462 degrees C, and glass transition temperatures (T-g) range from 78 to 127 degrees C. The investigation of photophysical properties of these compounds revealed that all these compounds are of high photoluminescence quantum yields (PLQY), particularly for compound 6, whose PLQY value was as high as 90.22%. To explore potential applications of these materials in organic light-emitting diodes (OLEDs), two devices with compounds 2 and 5 were fabricated. Both devices show excellent device performances with maximum current efficiency, maximum power efficiency and external quantum efficiency of 15.9 cd A(-1), 10.41 m W-1 and 8.4% for compound 2-based device and 10.1 cd A(-1), 5.81 m W-1 and 5.5% for compound 5-based device, respectively.
