The fluorescent compound N-substituted 2,6-bis(benzimidazol-2-yl)pyidine (1) has been synthesized. The fluorescent characteristics of the compound 1 and 2,6-bis(benzimidazol-2-yl)pyidine (2) and the complexes formed between the two compounds and different metal ions have also been investigated. The results show that the compound 1 possesses a specific ability to form complex with Cu(2+) ion, but the compound 2 have not such a property. It is proposed that the specific recognition ability of compound 1 to Cu(2+) may be attributed to the cyclic configuration of this compound in polar solvent.
荧光化合物N-取代的2,6-双(苯并咪唑-2-基)吡啶(1)已被合成。还研究了化合物1和2,6-双(苯并咪唑-2-基)吡啶(2)的荧光特性以及这两种化合物与不同金属离子形成的配合物。结果表明,化合物1具有与Cu(2+)离子形成配合物的特殊能力,但化合物2没有这种性质。有人提出,化合物1对Cu(2+)的特异性识别能力可能归因于该化合物在极性溶剂中的环状结构。
