CO 2 regulates molecular rotor dynamics in porous materials

A crystalline hydrogen-bonded framework with permanent porosity, built by rod-like struts and engineered to bear ultra-fast molecular rotors between two triple bonds, offers the possibility of controlling the rotational rates upon CO adsorption.

Description
Summary:A crystalline hydrogen-bonded framework with permanent porosity, built by rod-like struts and engineered to bear ultra-fast molecular rotors between two triple bonds, offers the possibility of controlling the rotational rates upon CO adsorption. CO enters the pores from the gas phase and reduces the rotational rates from the extremely fast regime of 10 Hz at 216 K to 10 Hz. The CO -rotor interaction was evident from the H NMR response to the dynamics of the rotors in contact with CO in the crystal structure.
