Microporous materials are widely used in catalysis, separations, and sensor applications. The introduction of compounds with specific magnetic, optical, or electrical properties should greatly expand the range of applications for these materials. In their Perspective, Turnbull and Landee highlight an unusual porous material reported by Halder et al., which illustrates the versatility of porous molecular solids. The "host-guest" material shows a striking change in its magnetic and optical properties when guest molecules are gained or lost from its pores. The material retains its crystallinity upon loss of the guest molecules and even upon their reabsorption.
