| 摘 要： | 以邻苯二胺和2-氯苯甲酸、4-甲氧基苯甲酸、2,6-吡啶二羧酸为原料,在多聚磷酸(PPA)的催化下,用微波辐射法分别合成2-(2-氯苯基)苯并咪唑、2-(4-甲氧基苯基)苯并咪唑和2,6-二(2-苯并咪唑基)吡啶.通过测定熔点、元素分析、红外光谱(IR)、核磁(1HNMR)及紫外光谱(UV)对这三种苯并咪唑类化合物进行了表征,并对合成工艺进行了初步探讨.荧光测试表明,这三种化合物分别在发射波长λ发射=364.0 nm、345.0 nm、376.0 nm处具有较强的蓝色荧光发射.

| Abstract: | The 2 - 2 - chlorophenyl） benzimidazole, 2-（4-methoxy benzyl） benzimin-azole and 2,6-bis（2-benzimidazolyl） pyridine were synthesized by the reaction of 1,2-diaminobenzene, 2-chlorobenzoic acid, p-anisic acid and 2,6-Pyridinedicarbox-ylic under microwave irradiation with PPA as catalyst. The product was characterized by the melting point determination, 1HNMR, IR spectrum and UV spectrum. The optimal reaction conditions were also studied. The AFS spectrums of the three compounds indicate the product has strong fluorescence-emis- sion at k~ =364.0 nm,345.0 nm,376.0 nm. |
