The invention discloses a bifurcate alkyl chain and a preparation and an application thereof in organic conjugated molecules. The bifurcate alkyl chain serving as a solubilization group is applied in preparing organic conjugated molecules (particularly organic conjugated polymers), the interval number m of a formed alkyl side chain and main methylene is larger than one, capable of reducing effects of the alkyl chain on main Pi accumulation, so that the solubility of the organic conjugated molecules is guaranteed, and the mobility ratio of current carriers is improved greatly, the bifurcate alkyl chain is suitable for being used as organic semiconductor materials in photoelectric devices of organic field effect transistors, organic solar cells, organic light emitting diodes and the like. |
