标题:亲核试剂诱导的光活化二芳基乙烯重排的灵敏测定
摘要:在光诱导异构化后,带有反应性醛部分的二芳基乙烯 (Dae) 在胺存在下选择性地重排,并伴有脱色.在一项综合研究中,探针结构根据其在亲核试剂触发的重排反应中的固有反应性进行了优化.可以推导出详细的结构-反应关系,特别是关于整合(杂)芳基部分的类型以及甲酰基残基的位置,并且优化了探针与伯胺和仲胺的固有反应性.利用辅助碱基,最初形成的重排产物可以参与随后的催化循环,导致放大的脱色过程.这种额外的催化途径使我们能够提高我们方法的灵敏度并成功区分胺和硫醇.此外,已设计出表现出强分析物诱导荧光调制的探针,以通过使用更灵敏的读数进一步降低检测限.优化的 Dae 探针是未来可编程传感材料和设备的有前途的分子组件.
