Description

technical field [0001] The invention relates to a supramolecular co-assembly and its preparation method and application, in particular to a calixarene-rhodamine supramolecular co-assembly and its preparation method and application. Background technique [0002] Supramolecular assembly is defined as a multi-molecular group composed of non-covalent bonds, which can be as simple as two molecules. They can be spherical, rod-shaped or flake-like complex organized aggregates, and maintain a certain integrity, so that they have well-defined microstructure and macroscopic properties. [0003] Supramolecular assemblies have a wide range of applications. For example, Samuel 1.Stupp of Northwestern University and his colleagues indicated that the supramolecular assembly of peptide amphiphiles into nanofibers can be used to promote the growth of neurons; and biological / Self-assembling dendritic dipeptides (Self-assembling dendritic dipeptides) in materials science, which form empty cy...
