Tailor-made design of J- or H-aggregated naphthalenediimide-based gels and remarkable fluorescence turn on/off behaviour depending on solvents

Abstract

A naphthalenediimide (NDI)-based new gelator molecule has been discovered, the molecule forms interesting J/H-aggregated species depending on solvents (aliphatic/aromatic) and remarkably, the fluorescence of the gel phase materials is nicely tuned according to the electron donating capacity of the aromatic solvent.
