Zusammenfassung: | 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.
Irreversible temperature sensing: crystalline to amorphous phase change leads to a dramatic increase in fluorescence output for this naphthalenediimide based molecule. |
