NH₂-MIL-53(Al): A High-Contrast Reversible Solid-State Nonlinear Optical Switch

Abstract

The metal-organic framework NH(2)-MIL-53(Al) is the first solid-state material displaying nonlinear optical switching due to a conformational change upon breathing. A switching contrast of at least 38 was observed. This transition originates in the restrained linker mobility in the very narrow pore configuration.
