Porous coordination solids such as metal-organic frameworks have received much attention in recent years for their potential applications in selective gas adsorption including CO2 capture, thanks in large part to their synthetic modularity and high porosity.  One challenge that remains is to design materials that can achieve high CO2 selectivity and adsorption capacity without significant energy penalty. We have been interested in developing a family of azo-containing 'smart' porous coordination solids that are capable of adjusting their pore structures in response to external stimuli such as gases and light. We show that some of these azo-incorporated materials have high CO2/N2 adsorption selectivity and thus may be suitable for CO2 capture application.
