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).

基于烷氧基取代水杨醛吖嗪的聚集诱导发射的新型荧光薄固体层的光物理性质

摘要 合成并表征了一系列直链和支链烷氧基取代的水杨醛吖嗪。由于聚集诱导发射 (AIE) 特性，所有衍生物都在薄层中表现出光致发光。由于取代基的性质，研究了通过蒸发、旋涂和喷墨印刷技术沉积的薄固体层中吖嗪的自组织能力。通过密度泛函理论（DFT）从理论上计算了电子特性，即轨道能量和由此产生的能隙。在选定的实例上制备喷墨油墨并印刷适合有机发光二极管 (OLED) 的光滑均匀荧光层。
