摘要: NMR diffusion measurements were used to probe the differences in characteristics of hexameric capsule [c]-undecane resorcin[4]arene (1b) a CDCl3 solution absence and presence tetrahexylammonium bromide (THABr). It was found that nonencapsulated THABr forms 1:1 complex with 1b, which is fast exchange its constituents. We water molecules seem not participate construction 1b solution, contrast finding THABr, where major species seems be [(1b)6(H2O)8].
