Method for applying optical switch polymorphic fluorescent supramolecular polymer to multiple data encryption

The invention discloses a method for applying an optical switch polymorphic fluorescent supramolecular polymer to multiple data encryption, which comprises the following steps: by taking methyl methacrylate, butyl acrylate, polymerizable photochromic diarylethene, polymerizable adamantane and azodiisobutyronitrile as raw materials, preparing an optical switch guest polymer and a guest polymer by adopting a free radical copolymerization method; photochromic spiropyrane and beta-cyclodextrin are used as raw materials to prepare the photoswitch host molecule. The object polymer and the host molecule are further combined through the host and the guest to obtain three supramolecular polymers, the three supramolecular polymers are respectively coated on a fan-shaped glass sheet to obtain a data encryption unit a, a data encryption unit b and a data encryption unit c, and the data encryption units a, b and c are used for multiple information encryption after permutation and combination.
