▎ 摘　　要

A multiple supramolecular assembly, in which a folic acid-modified beta-cyclodextrin (1) acted as a target unit, an adamantanyl porphyrin (2) acted as a linker unit, and graphene oxide acted as a carrier unit, was successfully fabricated through non-covalent interactions and comprehensively investigated by means of UV/Vis, fluorescence, and X-ray photoelectron spectroscopies, and electron microscopy. Significantly, the graphene oxide unit could associate with the anticancer drug doxorubicin through pi-pi interactions, and the folic acid-modified beta-cyclodextrin unit could recognize the folic acid receptors in cancer cells. Owing to the cooperative contribution of these three units, the resulting multiple supramolecular assembly, after association with doxorubicin, exhibited better drug activity and much lower toxicity than free doxorubicin in vivo.
