The invention relates to 2, 6-di(aryl)-anthraquinone and a preparation method thereof, the preparation method comprises the following steps: connecting electron donor or electron acceptor groups to the two sides of an anthraquinone ring in the 2 and 6 positions, and enabling a 2, 6-dibromo anthraquinone type derivative and a substituent group containing a vinyl group to generate an Heck reaction in alkaline conditions under the catalytic action of palladium acetate and tri-O-methoxy phosphorus for generating the 2, 6-di(aryl)-anthraquinone, and the general formula of the molecular structure of the 2, 6-di(aryl)-anthraquinone is shown in the specification, wherein R is the substituent group containing the vinyl group, the electron donor group or the electron acceptor group. As the compound has the larger conjugate plane and simultaneously has better photochemical stability, thermal stability and solubility, the compound can better capture multiple photons and excite the generation of multi-photon absorption and nonlinear absorption phenomena, and further meet the application requirements in the aspects of photoelectric conversion materials, nonlinear absorption materials and the like.
