The synthesis method of the intramolecular exciton splitting material comprises the following steps: synthesizing a molecule which takes benzopyrrolopyrroledione (BDPP) as a molecular skeleton and introduces different alkyl chain substituent groups on an amido bond nitrogen atom, wherein the skeleton has relatively strong blue-green light absorption, excellent air and light stability and appropriate triplet state energy. The invention discloses characterization means of the molecular solution and the thin film spectrum. The intramolecular exciton splitting material has an ultrafast-scale exciton splitting rate and a relatively high triplet state exciton yield, so that possibility is provided for application of a novel organic photovoltaic device to a great extent. The intramolecular exciton splitting (iSF) process in the BDPP molecule hardly depends on intermolecular orientation and electronic coupling, and the BDPP molecule has great potential to be integrated into an SF-based organic photovoltaic device.
