Dynamic Entangled Framework Based on an Iridium–Organic Unit Showing Reversible Luminescence Turn-On Sensing

A new entangled metal-organic framework shows reversible structural dynamics and luminescence changing in response to the loss of guest H2O molecules. Furthermore, an intense and sensitive luminescence turn-on sensing was observed by the naked eye for 1 upon detection of the volatile organic solvent molecule CH3CN, accompanied by reversible structural transformation.
