Herein, we present a systematic ligand\u2010engineering strategy for tailoring the hierarchical assembly of AuNPs into functional hybrid films, employing four structurally related 1,2,4\u2010triazole multidentate molecules of increasing coordination complexity under a unified solution compounding\u2013vacuum filtration\u2013thermal curing route. The results demonstrate that the type, number, and interplay of coordinating functional groups on the triazole scaffold govern the assembly architecture and interparticle plasmonic coupling, enabling a ligand\u2010programmed color\u2010tunable effect from wine\u2010red through purple and blue to gray\u2010brown.
