The invention relates to an 
organic semiconductor material containing 
naphthalene [1, 2-c: 5, 6-c] di [1, 2, 5] thiadiazole and application thereof, wherein the 
organic semiconductor material is prepared by reacting the halogenated derivatives with the 
monomer containing an aromatic group structure under the 
metal catalyst, wherein the halogenated derivatives are obtained by halogenating the 
naphthalene [1, 2-c: 5, 6-c] di [1, 2, 5] thiadiazole; the aromatic group is connected with a 
naphthalene [1, 2-c:5, 6-c] di [1, 2, 5] thiadiazole unit in a conjugate manner. The 
organic semiconductor material is characterized by containing 3, 7 substituted decorative[1, 2-c: 5, 6-c] di [1, 2, 5] thiadiazole 
chemical groups; as the naphthalene [1, 2-c:5, 6-c] di [1, 2, 5] thiadiazole has excellent 
electron-withdrawing ability and planarity, the organic 
semiconductor material can excellently adjust the photoelectric property, has excellent photoelectric performance, and is applied to the field of organic photoelectric components.
