A heteroditopic fluoroionophoric platform has been designed for constructing fluorescent probes for zinc ions over large concentration ranges. The responses of the prototype probes 3a and 3b to zinc ions were shown to be consistent with our hypothesis, according to which the modulation of photoinduced electron transfer followed by conformation rigidification or enhanced internal charge transfer of
设计了一个异位氟离子平台,用于构建大浓度范围内锌离子的荧光探针。原型探针3a和3b对锌离子的反应表明与我们的假设一致,根据该假设,光诱导的电子转移的调制,随后在连续的锌配位过程中,对位配体的构象刚性增强或内部电荷转移增强,提供了敏感的条件。一个波长通道中的荧光增强,随后发射带移至另一波长通道。在这项研究中建立的异二芳基芳基乙烯基双联平台为构建荧光探针提供了一种铅结构,该探针用于在宽动态范围内对锌离子进行实时活细胞成像。
