Abstract: Di-Schiff bases with alkyl spacer (ethyl, butyl and hexyl) showed enhanced light emitting properties in solid state, while quenching was observed for di-Schiff bases with hydrazine spacer. Packing of the molecules via non covalent interactions along with the flexible spacer played the role in dictating the emission properties.
