摘要
苝酰亚胺类衍生物是一类性能优异的N-型有机半导体材料~([1,2]),但是由于苝核之间很容易形成π-π堆积,而且当增大其共轭结构时,溶解性会变得更差,影响了其在有机电子学器件中的应用。我们设计合成了一种由四个苝酰亚胺单体通过港湾位的并环形成梯形结构形式星型树枝状共轭齐聚物分子。其中采用芴为树枝状分子的核,苝酰亚胺为枝。该梯形共轭齐聚物在常规溶剂中具有良好的溶解性,远远优于苝酰亚胺单体。通过热分析研究,发现该大分子具有很高的热稳定性;通过循环伏安法的测量,该分子具有很好的电化学稳定性:即便重复扫描15次,氧化还原电位曲线没有发生变化。而且在激光照射条件下测量荧光,发现该大分子表现出很好的光稳定性。通过SCLC测量,其表现出了很高的电子迁移率,并且将其作为一种非富勒烯类电子受体用于制作体相异质结太阳能电池器件中,采用常规的P3HT为给体,电池效率达到0.64%。
We have designed and synthesized a novel ladder-conjugated star-shaped oligomer of four PDI units and a fluorene core.The material is highly soluble in dichlorobenzene with the solubility of 155 mg/mL.And it exhibits good thermal stability with the decomposition temperature(T_d) of 291.2 ℃,electrochemical stability with cyclic voltammetry(CV) curves successive invariable scanning for 15 cycles and photostability with maintains 99%fluorescence intensity after irradiation for 10 min using maximum laser intensity.In order to evaluate its potential application,as a new N-type material,we measure its electron mobility and bulk heterojunction(BHJ) organic solar cells(OSCs).
