Paragraph 0093-0095, (2018/03/06)
The invention provides a dibenzocarbazole fused ring compound and an organic electroluminescent device thereof, and relates to the technical field of an organic optoelectronic material. A carbazoles structure is relatively high in redox potential value and excellent in stability in an air or lighting condition. Through introduction of a fused-ring rigid asymmetric and dense structure, the obtainedaromatic amines derivative is improved in thermal stability. The compound is used to prepare an organic electroluminescent device. Specifically, when the compound is taken as a main material in the organic electroluminescent device, the carbazoles main material having a rigid structure is high in glass-transition temperature, which is beneficial for prolonging the life of the organic electroluminescent device. The organic electroluminescent device shows high efficiency and low driving voltage, is not prone to crystallize, and is superior to a common OLED device.

Two fluorene-based boronic acids, 9,9-dimethyl-9H-fluoren-2-yl-2-boronic acid (1) and 9,9-dimethyl-9H-fluoren-2,7-diyl-2,7-diboronic acid (2), were synthesized and their sensing abilities for detection of D-monosaccharides were investigated by fluorescence at physiological pH. It was found that both boronic acids 1 and 2 have high selectivity and sensitivity for D-fructose with stability constant of 47.2 and 412.9, respectively. The sensor 2 showed a linear response toward D-fructose in the concentration range from 5 × 10-5 to 10-1 mol L-1 with the detection limit of 2 × 10-5 mol L-1.
