Single‐Crystal to Single‐Crystal Photochemical Structural Transformations of Interpenetrated 3 D Coordination Polymers by [2+2] Cycloaddition Reactions

Dual‐Emitting MOF⊃Dye Composite for Ratiometric Temperature Sensing

“…Such molecular sensing materials typically display unstable sensitivity . To assemble lanthanide ions with organic bridging linkers into lanthanide metal‐organic frameworks (MOFs) and/or coordination polymers (CPs), the solid lanthanide MOF/CP materials are very promising platforms to explore stable temperature sensors . Because different lanthanide ions can be rationally incorporated into the isostructural lanthanide MOFs/CPs, we can also make use of dual luminescent intensities from two different lanthanide ions (e.g., Tb 3+ and Eu 3+ ) to establish the self‐calibrated robust temperature sensors.…”

Single‐Crystal‐to‐Single‐Crystal Transformations of Two Three‐Dimensional Coordination Polymers through Regioselective [2+2] Photodimerization Reactions

“…SCSC transformations associated with photodimerization reactions involving ligands that are part of a three‐dimensional coordination network are extremely rare 6c. This is because positional and geometrical constraints placed upon bridging ligands, through their incorporation in a network structure, may not allow the reactive groups to come into the appropriate positions for the generation of new bonds.…”

Functionalization of Metal–Organic Frameworks for Photoactive Materials

“…In 2010, a photochemical [2 + 2] cycloaddition accompanying the SCSC transformations in MOFs was achieved by Lang et al They synthesized 1,4‐bis[2‐(4‐pyridyl)ethenyl]benzene (bpeb)‐based MOFs and implemented photoinduced‐cycloaddition reactions that were characterized by an SCSC analysis. Medishetty et al reported photochemical structural transformations in MOFs to alter the framework from a 2D interdigitated or 3D interpenetrated structure to 3D interpenetrated networks in an SCSC manner. A 2 to 3D porous network structure transformation via a quantitative, topochemical [2 + 2] cycloaddition in an SCSC manner was also reported by Xie et al and led to a porous MOF with interesting catalytic activity for phenylmethanol oxidation .…”
