Py‐IPH, a pyrene‐based fluorogen with good thermal and mechanical stability was simply prepared by the Schiff base reaction and applied in the detection of antimony. Py‐IPH presented special excimer fluorescence in the mixture of THF and water with 80 % of water, and exhibited perfect fluorescent response to antimony. The mechanism was demonstrated to be the increasing speed of the formation of pyrene excimers in the system owing to the coordination between antimony and IPH group in Py‐IPH. Moreover, based on the special interaction between Py‐IPH and antimony, it could distinguish antimony with other cations well with high specificity and selectivity.

具有特殊准分子荧光的Fluor基锑探针

Py-IPH是一种具有良好热和机械稳定性的a基氟，可以通过席夫碱反应简单制备，并用于锑的检测。Py‐IPH在THF和水与80％的水的混合物中表现出特殊的准分子荧光，并表现出对锑的完美荧光响应。机理被证明是由于Py-IPH中锑与IPH基团之间的协调，导致系统中of准分子的形成速度增加。此外，基于Py-IPH和锑之间的特殊相互作用，它可以高特异性和高选择性很好地将锑与其他阳离子区分开。
