摘要

Glycinylurea functionalized n-conjugated diphenylanthracene guests(DPA guests)that bind to adamantyl urea modified dendritic hosts were synthesized and fully characterized by NMR spectroscopy('H-NMR,13C-NMR)and MALDI-TOF-MS.The resulting supramolecular assemblies have been investigated with respect to their binding properties.DPA guests molecules were able to click into urea functionalized N,N-bis[(3-adamantyl ureido)propyl] methyl amine host as a result of acid-base(between COOH of the guest and amines of the host)and hydrogen bonding interactions(between the urea linkages of dendrimer and the guest).The guest molecules were bound as 1:1 inclusion complexes and the association constants for both guests have been calculated.Subsequently,an adamantyl urea modified fifth generation polypropylene imine)dendrimer was synthesized as a multivalent host which contains 32 N,Nbis[(3-adamantyl ureido)propyl] amine binding sites.Size exclusion chromatography showed that 32 of the DPA guests strongly bind to the fifth generation adamantyl functionalized dendritic host.
