Stimuli-Responsive Lanthanide–Dianthracene Frameworks: Lanthanide-Dependent Photocycloaddition Reaction and Photophysical Properties
Metal–organic frameworks (MOFs) showing stimuli-responsive optical properties are very attractive due to their potential applications in information storage, molecular switches, and devices. In this work, we report a series of isomorphic lanthanide–dianthracene phosphonates with layered framework structures, namely, [Ln(NO3)3(depma2)1.5]·(depma2)0.5 (1Ln, Ln = Nd, Sm, Eu, Gd, Tb, Ho, Er, Tm, Yb), where depma2 stands for prephotodimerized 9-diethyl-phosphonomethylanthracene (depma). 1Ln experiences a thermally induced single-crystal-to-single-crystal (SC–SC) structural transformation forming a chain compound [Ln(NO3)3(depma)(depma2)]·(depma2)0.5 (2Ln) in which one depma2 is dissociated into an anthracene pair. Interestingly, 2Ln (Ln = Sm, Gd, Tb, Tm, Yb) exhibit excimer emission and undergo [4 + 4] photocycloaddition of anthracene in an SC–SC fashion to form the pristine 1Ln, while the others either display a near-infrared (NIR) emission (for 2Nd, 2Er, 2Ho) or nonemissive (for 2Eu) and do not undergo photocycloaddition reaction. Obviously, reversible photoresponsive luminescence properties can be achieved for 2Ln (Ln = Sm, Gd, Tb, Tm, Yb) but not for 2Ln (Ln = Eu, Nd, Er, Ho).
期刊介绍：
The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials.
Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials. Synergistic approaches originating from different disciplines and technologies and integrating the fields of crystal growth, crystal engineering, intermolecular interactions, and industrial application are encouraged.
