ABSTRACT The restriction of the molecular motion has been extensively exploited in tailoring photoluminescence (PL) metal nanoclusters, while activation such a at level remains highly challenging. In this work, two‐step strategy, that is, surface activating and coupling, was proposed to induce nanoclusters level, corresponding underwent emission appearance enhancement. peripheral phosphine ligand functionalization alkali cation introduction gave rise series structural‐correlated M + ‐incorporated Cu 14 (M = Li, Na, K, Rb, Cs) with surface‐aggregation characteristic, among which K ‐participating nanocluster displayed strongest fluorescence intensity both solution crystal states. Atomic‐level structure–property correlations were investigated rationalize PL comparisons. Overall, work offers new perspective for regulating via restricting their motions, hopefully providing insight into fabrication emissive cluster‐based nanomaterials.
