Melt-induced fluorescent signature in a simple naphthalenediimide

The synthesis and fluorescence properties of a naphthalenediimide ditosylate are presented. The fluorescence is highly solvent and morphology dependent with a dramatic change in fluorescence output occurring following melting from a crystalline form. This observation is attributed to thermal disrupt...

Summary:The synthesis and fluorescence properties of a naphthalenediimide ditosylate are presented. The fluorescence is highly solvent and morphology dependent with a dramatic change in fluorescence output occurring following melting from a crystalline form. This observation is attributed to thermal disruption of the crystal structure allowing the formation of emissive dimers within the amorphous melt.
