Synthesis
of a small molecular cage consisting of three aminomethyl pyrroles and its selective
fluoride recognition Nam Jung Heo, Hye Jin Han, Jaewon Choi,* and Sung Kuk Kim* Department of Chemistry and Research Institute of Natural
Science, Gyeongsang National University, Received Oct 24, 2022; Accepted
Nov 8, 2022 Abstract 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. Keywords molecular cage, anion
recognition, fluoride, affinity, selectivity
