有机半导体材料具有低成本、可制备柔性器件等优点,广泛应用于有机薄膜光电器件。如今迫切需求同时具有较高迁移率和较好溶解性能可溶液加工的有机电子传输材料来支撑其发展。但分子的功能化使其刚性越来越大,溶解性能受到了影响。设计合成了N,N′-二苯基苝四羧基二酰亚胺(DiPP)和N-十二烷基-N′-苯基-苝酰亚胺(DoPP)两种苝酰亚胺衍生物,研究长链烷基对苝酰亚胺衍生物性能的影响。结果表明,长链烷基的引入大幅度提升了苝酰亚胺衍生物的溶解性能,但是其在空气中的热稳定性和抗氧化性有所降低。
Organic semiconductor materials are widely used in thin-film organic devices due to their advantages of low cost and flexible.There is an urgent need to support the development of organic semiconductor materials that have both high mobility and good solubility.However,the functionalization of molecules make it more rigid and solubility is limited.Two kinds of perylene imide derivatives,N,N′-diphenyl perylene tetracarboxylic diimide (DiPP) and N-dodecyl N′-phenyl perylene imide (DoPP) were synthesized to study the effect of long chain alkyl groups on the performance of perylene imide derivatives.The results showed that the introduction of long-chain alkyl greatly improved the solubility of perylene imide derivative,but its thermal stability and oxidation resistance in air decreased.
