초록
A small cage-like molecule (2) composed of three aminomethyl pyrroles and two hexa-substituted benzenes has been prepared by reduction of its iminopyrrole analogue (1) using NaBH4. It was revealed by 1H NMR spectroscopic analyses that cage molecule 2 strongly binds the fluoride anion in polar DMSO-d6 relative to CDCl3. Compared to that of compound 1, the lowered affinity of 2 for the fluoride anion is attributable to its increased electron density resulting from the production of thesecondary amine groups.
