Fluorescent nose: The reversible “turn‐on” vapochromism of a self‐assembled amphiphilicnaphthalenediimide derivative in solution and film states is presented. This property was found to be due to solvent–vapor‐responsive, dynamic reorganization in molecular packing in going from J‐type aggregates (blue fluorescent; see left‐hand side of scheme) to preassociated H‐type excimer states, with enhanced
