Halide functionality dependent formation of molecular receptors and their ion recognition properties.
The halide functionality on N-bridged tripodal receptors has shown a distinct behavior on their self-assembly structures and binding ability toward HgCl(2) and ClO(4)(-) anions. The receptors containing fluoro, chloro, and iodo groups crystallized to form hemicarcerands in the solid state, whereas the receptor with a bromo group forms a molecular capsule via C-H...Br and C-H...pi interactions. The cavity of the molecular capsule is tunable and is capable of reversible encapsulating-releasing the guest molecules by pH modulation.
