Dual image storage material as well as preparation method and application thereof

A dual image storage material, wherein the dual image storage material is obtained by selective photoreaction of a composition comprising:

• an organic fluorescent material,
• a liquid crystal,
• a photoinitiator, and
• a photopolymerizable monomer,
• wherein the photopolymerizable monomer is a mixture of a monofunctional monomer and a polyfunctional monomer, the monofunctional monomer has a single carbon-carbon double bond, and the polyfunctional monomer has multiple carbon-carbon double bonds,
• the organic fluorescent material includes one or more compounds selected from the group consisting of substituted 1,1,2,2-tetraphenylethene (TPE), substituted 1,1,2,3,4,5-pentaphenyl-1H-pyrrole, substituted 1,1,2,3,4,5-hexaphenyl-1H-silole (HPS), substituted 9,10-di[(E)-styryl]anthracene (DSA), substituted 10,10′,11,11′-tetrahydro-5,5′-bidibenzo[a,d][7]annulenylidene (THBA), substituted benzhydrylidenefluorene, and substituted 2,2′-(2,6-diphenylanthracene-9,10-diylidene)dimalononitrile (PDAB),
• where the substituent groups R in the structural formulae are each independently selected from the group consisting of n-hexyl, n-amyl, citronellol group, 4′-heptyl-4-biphenylcarbonitrile, 4′-(octyloxy)-4-biphenylcarbonitrile, 4-cyano-4′-pentylbiphenyl, and 4-butoxy-[1,1′-biphenyl]-4′-carbonitrile.
