preparation example Construction

[0070] The key step of the preparation method of the nano-lattice of the present invention is that the tertiary alcohol undergoes an acid-catalyzed Friedel-Crafts reaction, and the nano-lattice is obtained by self-ring closure. Taking nanolattice I as an example, the specific reaction is as follows:

[0071]

[0072] This type of material is obtained by polymerization of nano-lattice through Suzuki coupling polymerization, Stille coupling polymerization or Yamamoto coupling. Taking nano-polymer lattice material II as an example, the details are as follows:
