Non-covalent self assembly controls the relaxivity of magnetically active guests.

Vincent Li¹, Yoo-Jin Ghang, Richard J Hooley, Travis J Williams.

Abstract

The relaxivity of a magnetically responsive Gd complex can be controlled by non-covalent molecular recognition with a water-soluble deep cavitand. Lowered relaxivity is conferred by a self-assembled micellar "off state", and the contrast can be regenerated by addition of a superior guest.
