Hydrogen‐Bonding‐Mediated J‐Aggregation and White‐Light Emission from a Remarkably Simple, Single‐Component, Naphthalenediimide Chromophore

Abstract

Almost pure white-light emission (fluorescence quantum yield=0.70) from a remarkably simple single-component, carboxylic acid appended naphthalenediimide (NDI) derivative has been reported. Aggregation-induced modulation of photophysical properties was attributed to hydrogen-bonding-mediated J-type π stacking among the NDI chromophores.
