Embodiment
[0026] A nano-supramolecular assembly of permethylated β-cyclodextrin-modified hexabenzocoronene derivatives, the chemical formula of which is C 184 h 248 N 6 o 70 , its chemical structure is as follows:
[0027]
[0028] The supramolecular assembly is constructed through intermolecular π-π interactions, and its morphology scale is a nanoscale, rod-like aggregate; the preparation method steps are as follows:
[0029]1) Dissolve 200mg of propynyl-modified hexaphenylbenzene and 910mg of 6-deoxy-6-amino-permethylated-β-cyclodextrin in 50mL of N,N-dimethylformamide, add 47.5mg of iodide Cuprous, then heated to 80°C under the protection of nitrogen to react for 48 hours, filtered, spin-dried, and performed column chromatography with a mixed solution of dichloromethane and methanol at a volume ratio of 20:1 to obtain white permethylated β-cyclodextrin modified hexaphenylbenzene;
[0030] 2) Dissolve the above-mentioned 400 mg of permethylated β-cyclodextrin-modified hexaphen...
