NOVELTY - A supramolecular-type organic solar battery material includes four basic structural units of a donor unit, a receptor unit, a connection unit and a self-assembly unit. The self-assembly unit is thiophene, phenylacetylene, biphenyl, aromatic amine, polycyclic aromatic compound, phthalocyanine or their derivative. The receptor unit is fullerene, perylene, carbon nanotube or their derivative. The selection of connection unit is divided into two categories such as an insulating type and a connecting type according to energy grade matching circumstances.    USE - Supramolecular-type organic solar battery material.    ADVANTAGE - The supramolecular-type organic solar battery material has improved energy conversion efficiency.    DETAILED DESCRIPTION - A supramolecular-type organic solar battery material includes four basic structural units of a donor unit, a receptor unit, a connection unit and a self-assembly unit. The connection unit and self-assembly unit have same or different molecular structures. The self-assembly unit is thiophene, phenylacetylene, biphenyl, aromatic amine, polycyclic aromatic compound, phthalocyanine or their derivative. The receptor unit is fullerene, perylene, carbon nanotube or their derivative. The selection of connection unit is divided into two categories such as an insulating type for blocking the movement of electrons and holes, and a connecting type which enables electron transfer when the receptor is activated, hole transfer when the donor is activated, and electron and hole transfer when the connection group is activated, according to energy grade matching circumstances. An INDEPENDENT CLAIM is included for preparation of supramolecular-type organic solar battery material, which involves preparing monobromide or dibromide active reaction intermediate of donor, receptor, connection and self-assembly structural units respectively by typical halogenated reaction, performing Suzuki, Grignard and Wittig reactions to obtain target material molecule, performing catalyst-initiating polymerization reaction or ultra-light-initiating polymerization reaction if the molecular structure is high molecule, dissolving the molecular materials into mixed solvent having different polarities, reacting under hot condition, reflowing, reducing the temperature to 0-10 degrees C, and realizing self-assembly of molecule to obtain target supramolecular material. The reaction intermediate is connected sequentially to the target material molecule by coupling reaction, and then the target supramolecular material is formed by molecular self-assembly.
