Smart Lanthanide Metal–Organic Frameworks with Multicolor Luminescence Switching Induced by the Dynamic Adaptive Antenna Effect of Molecular Rotors
Guangxi University · Guangxi Normal University
Abstract
Abstract In this work, dynamic molecular rotors are used to construct smart lanthanide metal–organic frameworks ( Ln‐MOFs ) emitters with adaptive antenna effects for the first time. The movement or distortion of the molecular rotors can be easily regulated by temperature changes, thereby inducing a dynamically changing antenna effect that can automatically match different lanthanide ions, achieving cyclic multicolor luminescence switching behavior and extremely complex multiple encryption anti‐counterfeiting technology. In addition, by regulating the doping ratios of Gd(III) and Tb(III) with Eu(III) within the Ln‐MOFs , differentiated energy transfer pathways are discovered, and red light emission very close…
