摘要

摘要以吩噻嗪和芳香二胺为基础，合成了在常见有机溶剂中具有良好溶解度的聚亚甲胺型共轭聚合物聚(PZ-PI)。聚PZ-PI在415 nm和510 nm处的紫外吸收最大值(λmax,UV)和边缘(λedg,UV)分别被观察到。ITO/polymer/Mg和ITO/polymer/Alq3(100 Å)/Mg器件的阈值电压分别为10 V和7 V。此外，与单层LED相比，Alq3双层LED的发光强度和效率都有所提高。

Synthesis of Polyazomethine Type Conjugated Polymers as Light Emitting Materials

Abstract Aromatic dialdehyde based on phenothiazine and aromatic diamine were used to synthesize polyazomethine type conjugated polymer, poly(PZ-PI) which had good solubility in common organic solvents. The UV absorption maximum(λmax,UV) and edge(λedg,UV) of poly(PZ-PI) were observed at 415 and 510 nm, respectively. The threshold voltage of ITO/polymer/Mg and ITO/polymer/Alq3(100 Å)/Mg device was at 10 V and 7 V, respectively. Besides double layer LED with Alq3 exhibited both enhanced emission intensity and efficiency compared to the single layer LED.
