method. Compound 1 features a 1-D double [Cu2I2] chain anchoring the MA molecules on both sides of the chain with uncoordinated amino and heterocyclic nitrogen groups as recognition sites to interact with guest molecules. Compound 1 exhibits excellent thermal stability and is also stable in acidic and basic media. As a fluorescent sensor, compound 1 was successfully used for the detection of NACs such
通过溶剂热法制备具有式[Cu 2 I 2(MA)2 ](MA =
三聚氰胺)(1)的荧光配位聚合物。通过纳米沉淀法获得1的纳米尺寸。化合物1具有一维双[Cu 2 I 2 ]链,该链将MA分子锚定在链的两侧,并带有未配位的
氨基和杂环氮基作为与客体分子相互作用的识别位点。化合物1具有出色的热稳定性,并且在酸性和碱性介质中也很稳定。作为荧光传感器,化合物1已成功用于检测
NAC,例如2,4,6-三
硝基苯酚(
TNP),
硝基苯(NB),
对硝基苯酚(4-NP),
2,4-二硝基甲苯(
2,4-DNT)和2
水溶液淬灭后的1,4-
二硝基苯酚(
2,4-DNP)。淬灭序列为
TNP> 2,4-DNP> 2,4-DNT> 4-NP> NB。此外,随着1的粒径减小,感测灵敏度增加。
TNP的检出限为0.717μM。我们还讨论了基于理论计算和紫外可见吸收光谱的可能的淬灭机理。
