The present invention relates to the synthesis method of A-D-A type organic optoelectronic small molecules based on perylene diimide and pentacene. Benzene‑2,9‑dipinacol ester or 6,13‑bis(triisopropylsilylethynyl)pentacene‑2,10‑dipinacol ester dissolved in 1‑bromoperylenediimide In a solvent, under the action of a catalyst, 2,10-diperylenediimide-6,13-bis(triisopropylsilylethynyl)pentacene or 2,9-diperylene is obtained through a coupling reaction Imide-6,13-bis(triisopropylsilylethynyl)pentacene, and then under the action of iodine simple substance, illuminate with LED light, and prepare the final product through photocyclization reaction. The invention is the first to assemble an electron acceptor material with excellent performance and a model molecule of singlet fission into one molecule, which can be applied in the fields of organic solar cells, field effect transistors, photodetectors and organic light emitting diodes. |
