Keeping limber: Three-dimensional coordination polymers incorporating flexible pillars (see picture, left) exhibit highly selective adsorption of CO2 over N2, H2, and CH4 (see picture, right), thermal stability up to 300 °C, as well as air and water stability, and allow efficient CO2 capture, storage, and sensing.
