The invention relates to an organic conjugated small molecule material containing a thianthracene end group and a preparation method thereof. The end group of the organic conjugated small molecule material contains a thianthene group, which has a large conjugation area and a sulfur atom substitution group, which is beneficial to the self-assembly and stacking of the molecules, thereby improving the photovoltaic performance of the small molecule material. It has good thermal stability, good light absorption and suitable energy level, and is soluble in organic solvents such as chloroform, dichloromethane, tetrahydrofuran and chlorobenzene; it is suitable for solution processing to prepare organic solar cell devices. As an electron acceptor material, this type of material can be used in organic solar cell devices, and good device effects can be obtained. |
