Monohydrate-4-(4-dimethyl amino styryl) methylpyridine benzene sulfonate and preparation method thereof

The invention belongs to the technical field of functional materials and a preparation method thereof, and relates to monohydrate-4-(4-dimethyl amino styryl) methylpyridine benzene sulfonate and a preparation method thereof. A pi electronic conjugate system exists in a molecular structure of the monohydrate-4-(4-dimethyl amino styryl) methylpyridine benzene sulfonate; a single crystal diffraction test result shows that the chemical formula of the sulfonate is C22H24N2O3S.H2O which belongs to a triclinic system under the room temperature, and has a space group of P-1, and cell parameters of: a=9.7736(10)angstrom, b=13.9411(14) angstrom, c=16.7501(17) angstrom, alpha=106.1087(12) degrees, beta= 91.3577(12) degrees, gamma= 105.0583(12) degrees, V=2106.07(40)angstrom and Z= 4. The preparation process includes four steps of synthetic reaction, condensation reaction, ion exchange reaction and filtration and purification. Moreover, heat stability is good, purify is high, materials are easily available, preparation m
