Abstract: This application relates to the field of electro-optic materials, and provides a chromophore and a method for preparing the chromophore, and an organic electro-optic material and application of the organic electro-optic material. The chromophore includes a conjugated bridge, and an acceptor and a donor respectively connected to two ends of the conjugated bridge via chemical bonds. The acceptor is 2-dicyanomethylidene-3-cyano-4-methyl-5,5-bis(4-fluorophenyl)-2,5-dihydrofuran. The chromophore provided in this application has a high β value and good chemical and thermal stability.
