Abstract
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.
