Liquid crystal polymer with continuously adjustable fluorescence color and preparation method thereof

The invention relates to a liquid crystal polymer with continuously adjustable fluorescence color and a preparation method thereof, the preparation method comprises the following steps: firstly, obtaining two cyano-substituted position-isomeric cyano-stilbene monomers through a series of organic synthesis means, and then obtaining a random copolymer based on cyano-stilbene through a free radical polymerization method, wherein due to the similar chemical structures of the two kinds of position isomerism cyanostilbene elements, a uniform liquid crystal phase structure can be formed through ordered co-assembly; the isomerism of the cyano position enables the two cyano stilbene elements to generate large fluorescence difference, so that in the copolymerization process of different proportions, an orderly assembled liquid crystal structure can be maintained, and the liquid crystal polymer with continuously adjustable fluorescence can be obtained by changing the copolymerization proportion.
