Pyrene-Tagged Polyimidazolium Nanoclays Enable Modular Excimer Emission for Multi-Analyte Fluorescence Sensing

We introduce a modular platform for engineering excimer-active fluorescent nanoclays by covalently installing pyrene onto imidazolium-functionalized polyionic nanoclays (PINCs) using thiol-maleimide Michael addition. Precise control of pyrene surface densities (0.1–15 mol %) affords a synthetically tunable monomer–ex...
