摘要
在控制反应温度的条件下,用罗丹明B酰肼(或罗丹明B乙二胺)选择性分步取代三聚氯氰环上的活性氯,合成了系列罗丹明-三嗪衍生物.考察了不同取代获得的衍生物的探针识别性能,发现所制备的衍生物能高灵敏、高选择性地识别Al3+,Cr3+或Cu2+离子,是一类性能良好的金属离子荧光和比色增强型探针.
A series of rhodamine-triazine derivatives was synthesized through the substitution of active chlorine of cyanuric chloride step by step with rhodamine hydrazide(or rhodamine ethylenediamine). The recognition performances of derivatives were studied. Different substituted derivatives can recognize Al^3+, Cr^3+ or Cu^2+ with high sensitivity and selectivity. They were a kind of good performance of metal ion fluorescence and color enhanced probes.
