为了开发高强度的有机电致发光材料,在吡唑的1位上引入苯基以及苯并噻唑基,在3位上引入芳基,在4位上引入醛基。用一步法合成了1,3,4-噁二唑,并通过Wittig反应将噁二唑与4-甲酰基吡唑相连合成了6种未见报道的口恶二唑类化合物,用红外光谱、质谱、核磁共振谱和元素分析对合成化合物进行了结构表征。用荧光光谱仪对它们的荧光性能进行了测试,所合成化合物的荧光性能较好,荧光发射波长在410~440nm之间,并且荧光量子产率最高能达到0.68。
In order to develop a high-intensity organic electroluminescent material, a phenyl group and a benzothiazolyl group are introduced at the 1-position of the pyrazole, an aryl group is introduced at the 3-position, and an aldehyde group is introduced at the 4-position. One-step synthesis of 1,3,4-oxadiazole, and by Wittig reaction oxadiazole and 4-formylpyrazole linked into 6 kinds of previously reported oxazoles oxazoles compounds, by infrared spectroscopy, The structures of the synthesized compounds were characterized by MS, 1HNMR and elemental analysis. Their fluorescence properties were tested by fluorescence spectroscopy. The synthesized compounds showed good fluorescence properties with fluorescence emission wavelengths of 410-440 nm and their fluorescence quantum yields up to 0.68.
