Nitroxyl radical-containing flexible porous coordination polymer for controllable size-aelective aerobic oxidation of alcohols.

The ability of flexible porous coordination polymers (PCPs) to change their structure in response to various stimuli has not been exploited in the design of tunable-selectivity catalysts. Herein, we make use of this ability and prepare nitroxyl radical-containing flexible PCP that can reversibly switch between large- and contracted-pore configurations in response to solvent change and thus promote the controllable size-selective aerobic oxidation of alcohols.
