The invention discloses a compound having branching alkyl chains, the method for preparing the same and use thereof in photoelectric devices. By applying the branching alkyl chains as the solubilizing group to the preparation of organic conjugated molecules (for example, organic conjugated polymers), the number of methylenes between the resultant alky side chains and the backbone, i.e., m>1, which can effectively reduce the effect of the alkyl chains on the backbone π-π stacking, thereby ensuring the solubility of the organic conjugated molecule while greatly increasing the mobility of their carriers. It is suitable for an organic semiconductor material in photoelectric devices such as organic solar cells, organic light emitting diodes and organic field effect transistors, etc.
该发明公开了一种具有支链烷基链的化合物,以及其制备方法和在光电器件中的应用。通过将支链烷基链作为溶解基团应用于有机共轭分子(例如有机共轭聚合物)的制备中,结果烷基侧链与骨架之间的亚甲基数,即m>1,可以有效减少烷基链对骨架π-π堆积的影响,从而确保有机共轭分子的溶解性,同时大大增加其载体的迁移率。它适用于光电器件中的有机半导体材料,如有机太阳能电池、有机发光二极管和有机场效应晶体管等。
