Title: Controlling Structure Beyond the Initial Coordination Sphere: Complexation-Induced Reversed Micelle Formation in Calix[4]pyrrole-Containing Diblock Copolymers

Journal Article · · Journal of the American Chemical Society
DOI:https://doi.org/10.1021/jacs.8b09620· OSTI ID:1615751

A diblock copolymer containing a strapped calix[4]pyrrole-based ion pair recognition subunit has been synthesized via RAFT polymerization. As prepared, the polymer is hydrophobic and devoid of any particular morphological form. Yet, upon ion pair complexation, the copolymer self-assembles to generate reverse micelles in organic media. The reverse micelle formed in this way may be used to extract alkali cation and cesium halide anion salts from an aqueous source into an organic receiving phase. The polymer confirmed more effective as an extractant than the corresponding free ion pair receptor.
