摘　　要：以2-氨基-4,6-二甲基嘧啶与4-羟基苯甲醛为原料,合成了一种新型的含N有机盐型化合物。通过元素分析、FT-IR、1H NMR及13C NMR对目标化合物的分子结构进行了表征确证,并对目标化合物的UV-Vis、溶液荧光、固体薄膜荧光性能及热稳定性进行了研究。结果表明,目标化合物具有230、285 nm两处最大紫外吸收峰;在335 nm波长光激发下,目标化合物发射λ_(max)=454 nm的蓝色溶液荧光和λ_(max)=465 nm的固体薄膜荧光。该有机盐具有良好的热稳定性和较宽的熔盐温度区间,具有用作离子液体和DES反应介质的应用前景。A novel organic salt was synthesized with 4-hydroxybenzaldehyde and 2-aminobenzimidazole as raw materials.The target compound was characterized by means of elemental analyses,FT-IR,1H NMR,and 13C NMR.The properties including UV-Vis,photoluminescence and themal stability of the target compound were investi-gated.The results show that this salt has two UV absorption belt with the _(max)imum peak of 230 and 285 nm.Theλ_(max)=454 nm of blue fluorescence emission in ethanol andλ_(max)=465 nm in solid can be obtained under the excitation wavelength 335 nm.This organic salt possesses excellent thermal stability and has the potential used for ionic liquid and Deep-eutectic Solvent(DES).
