The present invention relates to a novel indenofluorene-6,12-dione derivative, and the structural formula of the derivative is shown in the following compounds 1, 2a, 2b and 2c: . The invention designs and synthesizes indenofluorene-6,12-dione derivatives modified with different alkyl chains, and flexibly introduces alkyl chains of different lengths into the molecule, which not only improves the solubility of the molecule, but also makes it easy to dissolve It is easy to purify in most organic solvents; it can also study the influence of substituents on the properties of compounds. The invention systematically studies the relationship between the structure and properties of molecules, provides certain guidance for the design of organic functional molecules, and provides a new material source for organic field effect transistors. |
