A chiral supramolecular liquid crystal based on pillararene and its application in information encryption

A chiral supramolecular liquid crystal based on a pillararene mesogen was constructed. The regulation of liquid crystal behavior was achieved through the host-guest interactions between the pillararene-based mesogen and a tetraphenylethylene-containing guest. In addition, this supramolecular liquid...

Description
Summary:A chiral supramolecular liquid crystal based on a pillararene mesogen was constructed. The regulation of liquid crystal behavior was achieved through the host-guest interactions between the pillararene-based mesogen and a tetraphenylethylene-containing guest. In addition, this supramolecular liquid crystal system, showing pH-responsive fluorescence emission character, was applied as an information encryption material capable of storing multiple levels of distinct information, thereby enriching the application of liquid crystal materials in the field of information security. A chiral supramolecular liquid crystal, constructed by host-guest complexation between a pillararene mesogen ( P5-Chol ) and a tetraphenylethylene-containing guest ( TPE-CN ), was applied in the field of multi-level information encryption.
