Abstract

A series of salicylaldehyde azines substituted with linear and branched alkoxy chains were synthesized and characterized. All derivatives exhibited photoluminescence in the thin layers due to Aggregation Induced Emission (AIE) properties. Ability to self-organizing of the azines in the thin solid layer deposited via evaporation, spin-coating and inkjet printing techniques, due to the nature of the substituent was investigated. The electronic properties, that is, orbital energies and resulting energy gap were calculated theoretically by density functional theory (DFT). On the selected examples inkjet inks were prepared and printed smooth uniform fluorescent layers appropriate for organic light emitting diodes (OLEDs).
