Mechanical grinding of a single-crystalline metal-organic framework triggered emission with tunable violet-to-orange luminescence.
A metal-organic framework (MOF) featuring intriguing Borromean entanglement exhibits a unique mechanochromic luminescence with on-off switching. The concomitant excitation wavelength-dependent emission behavior can be utilized to tune the emission color from violet to orange.
