| 英文摘要 | an extra-large octahedral coordination cage (ciac-114) was designed and modeled based on co-4-p-tert-butylsulfonylcalix[4]arene (co-4-(sc4a-so2)) subunits and 4,4',4''-(benzene-1,3,5-triyl-tris(benzene-4,1-diyl))tribenzoate (bbb) ligands via the isomorphic replacement approach built from an analogous cage structure with a smaller size. x-ray crystallography revealed that the crystals obtained through solvothermal synthesis exhibited the anticipated structure. each ciac-114 cage is assembled by six tetranuclear co-4-(sc4a-so2) units as vertices, which bear a four-fold rotational symmetry, and eight tripodal bbb ligands as linkers, which hold a d-3h symmetry. among its analogues ciac-114 has the largest overall peripheral diameter of 5.4 nm and an internal cavity of 2.7 nm. after treatment by supercritical co2, a single crystal sample of ciac-114 transformed into amorphous material with the retention of the cage skeleton, which demonstrated good adsorption properties towards a small drug molecule, ibuprofen (ibu), evidenced by ir spectroscopy, h-1 nmr spectroscopy, n-2 sorption analysis, and drug release experiments. the ibu release experiment in phosphate buffered saline solution (ph = 7.4) revealed that ciac-114 exhibited a slow drug release behavior. |
