摘要
Molecular recognition of aromatic hydrocarbons by four endo-functionalized molecular tubes has been studied by H-1 NMR spectroscopy, computational methods, and single crystal X-ray crystallography. The binding selectivity is rationalized by invoking shape complementarity and dipole alignment. The non covalent interactions are proved to predominantly be C/N-H center dot center dot center dot pi interactions.
