摘　　要：利用硫杂杯[4]芳烃衍生物与罗丹明乙二胺发生酰化反应,合成了2个具有双罗丹明基团的1,3-硫杂杯[4]罗丹明乙二胺酰胺衍生物。在实验条件下,衍生物与Fe3+均能形成1∶1配合物,配合物的形成诱导了衍生物分子中罗丹明基螺环开环,而表现出良好的荧光和比色探针性能。1,3-硫杂杯[4]罗丹明酰胺-2,4-酯对Fe3+的选择性高于1,3-硫杂杯[4]罗丹明酰胺-2,4-酸。光谱法考察了探针对Fe3+响应的分析特征,测定了合成样品。The two di-substituted rhodamine-based thiacalix[4]arene ethyldiamine amide derivative were synthesized from thiacalix[4]arene and rhodamine B ethyldiamine by acylation.Under the experimental conditions,the derivatives and Fe3＋ are able to form a 1∶1 complex.The formation of complex leaded to the moiety opening of rhodamine,and showed the good fluorescent and colorimetric performance.Among them,the selectivity of 1,3-thiacalix[4] rhodamine ethylenediamine amide-2,4-ester to Fe3＋ is higher than 1,3-thiacalix [4] rhodamine ethylenediamine amide-2,4-acid.The analysis feature of the probes response to Fe3＋ was studied by spectroscopy,and synthetic samples were determinec.
