Special Issue Information

Dear Colleagues,

In recent decades, Metal–Organic Frameworks (MOFs) have become a mature and dynamic technology within materials science. Since their discovery in the mid-1990s, this field of study has experienced exponential growth, yielding innovative structures, patents, and thousands of articles exploring applications such as sorption, luminescence, magnetism, catalysis, energy storage and conversion, drug delivery, and more. The intrinsic porosity, high surface area, thermal and chemical stability, and functionalization of MOFs make them versatile crystalline materials for the development of advanced devices and novel composites.

In the realm of opto-magnetic applications, MOFs have been employed in chemical and thermal sensing, biosensing, photocatalysis for water treatment, molecular magnets, magnetic resonance imaging, and photothermal and photodynamic therapies, offering a promising alternative to cancer treatment and antimicrobial applications.

This Special Issue aims to showcase recent advances in MOFs and related composite materials, focusing on innovative synthesis methods, shape and size engineering, and novel structures and properties with applications in opto-magnetic fields.

A set of three-dimensional metal-organic frameworks, named MOF-76, belonging to the tetragonal P4322 space group, based on [Y(BTC)(H2O)](DMF)1.1 (1,3,5-benzenetricarboxylate) doped with Eu3+, Tb3+, and Eu3+/Tb3+ were obtained under solvothermal conditions and fully characterized by powder X-ray diffraction, thermal, and vibrational analyses. In addition, upon UV light excitation (280 nm), all the powdered samples exhibited fine 4f-4f transitions, of which the 5D07F2 (Eu3+) and 5D47F5 (Tb3+) were the most intense ones. All samples were photophysically analyzed by determining the luminescence lifetimes, and their emission colors were quantified by calculating their chromaticities and color purities. Moreover, the intrinsic quantum yield, radiative, and non-radiative constants were calculated and compared to establish a structure–property relationship. Specifically, the Eu/Tb co-doped sample was employed to monitor its hypersensitive emissions in the presence of small volatile organic compounds (VOCs), showing quenching or enhancement of emission in protic and non-protic solvents. Furthermore, DFT calculations were carried out to understand the energy transfer processes between the sensor and the respective analytes. These results are promising for the development of solid-state lighting devices and colorimetric chemical sensors for specific compounds. Full article
