COMPOUND WITH BRANCHING ALKYL CHAINS, METHOD FOR PREPARING THE SAME, AND USE THEREOF IN PHOTOELECTRIC DEVICE

摘要

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.
