Tetrachloridometallate Dianion-Induced Cucurbit[8]uril Supramolecular Assemblies with Large Channels and Their Potential Applications for Extraction Coating on Solid-Phase Microextraction Fibers

Q[8]-based porous materials were synthesized in the presence of [Md‑blockCl4]2– anions as structure inducers. The driving forces of the structure-directing effect of the [Md‑blockCl4]2– anions may be due to the ion–dipole interaction and hydrogen bonding between the [Md‑blockCl4]2– anions and CH or...

Description
Summary:Q[8]-based porous materials were synthesized in the presence of [Md‑blockCl4]2– anions as structure inducers. The driving forces of the structure-directing effect of the [Md‑blockCl4]2– anions may be due to the ion–dipole interaction and hydrogen bonding between the [Md‑blockCl4]2– anions and CH or CH2 groups on the backs of Q[8] molecules. Moreover, the tests of potential applications show that these porous materials can not only capture organic molecules through the cavity of Q[8] moieties but also adsorb larger organic molecules with different selectivities.
