Description

Technical field [0001] The invention belongs to the technical field of supramolecular fluorescent sensing film materials, and specifically relates to a dihydroxy-containing amphiphilic binaphthyl derivative, as well as a preparation method and application of the derivative. Background technique [0002] Chirality is a ubiquitous phenomenon in nature. Most important biological macromolecules have chirality, and many important life processes involve specific interactions between chiral substances. In addition, most modern drugs and drugs under development are single enantiomers of chiral compounds, and they tend to have higher efficacy and lower toxicity than similar drugs. For example, (1R, 2R)-cyclohexanediamine is used as an important intermediate in the synthesis of oxaliplatin, and is often used as a common anti-cancer drug in oncology. In addition, most asymmetric synthesis involves the synthesis of chiral catalysts, and (1S,2S)-cyclohexanediamine can be used as a chiral sou...
