摘要

我们报道了一种新型氯化铟配合物，它表现出聚集诱导发射（AIE），并作为全氟烷基物质（PFAS）的选择性关闭荧光化学传感器。该配合物与全氟庚酸（PFHpA）和全氟辛酸（PFOA）相互作用时，由于基态分子轨道相对于激发态分子轨道的稳定，表现出强烈的蓝移发光猝灭。这些化合物对PFOA和PFHpA的选择性也反映在偶极矩和该复合物的发射强度上，因此，它们代表了有希望的传感“永远的化学物质”的平台。

Aggregation-induced emission-active indium complex as fluorescent turn-off chemosensor for perfluoroalkyl substances†

We report a novel indium(iii) chloride complex that exhibits aggregation-induced emission (AIE) and functions as a selective turn-off fluorescent chemosensor for perfluoroalkyl substances (PFAS). The complex shows strong blue-shifted luminescence quenching upon interaction with perfluoroheptanoic acid (PFHpA) and perfluorooctanoic acid (PFOA) due to stabilization of the ground state molecular orbitals relative to those of the excited state. The selectivity of these compounds for PFOA and PFHpA is also reflected in the dipole moment and thus emission intensity of this complex, hence, they represent promising platforms for sensing “forever chemicals”.
