Abstract

) with detection limits of 407 and 162 μM, respectively, whereas acidic amino acids perturb the emission only weakly. The response is fully recyclable over 10 cycles and post-sensing XPS shows preserved coordination environments. This work demonstrates that electronically active linkers can simultaneously stabilize silver nanocluster frameworks against aqueous degradation and encode molecular selectivity, opening a modular route to robust, programmable luminescent sensors.
