Duarte AnaniasMetal–organic frameworks based on trivalent lanthanides (LnMOFs) are a very promising class of materials for addressing the challenges in engineering of luminescent centres. Lanthanide-bearing phosphors find numerous applications in lighting, optical communications, photonics and biomedical devices. In this critical review we discuss the potential of LnMOFs as multifunctional systems, which combine light emission with properties such as microporosity, magnetism, chirality, molecule and ion sensing, catalysis and activity as multimodal imaging contrast agents. We argue that these materials present a unique chance of observing synergy between several of these properties, such as the coupling between photoluminescence and magnetism. Moreover, an integrated approach towards the design of efficient, stable, cheap, environmentally-friendly and multifunctional luminescent LnMOFs is still missing. Although research into LnMOFs is at its early stage and much basic knowledge is still needed, the field is ripe for new ideas, which will enable sensor devices and photonic prototypes to become a commercial reality (81 references).

José CavaleiroJoão RochaMetal–organic frameworks (MOFs), also known as coordination polymers, are formed by the self-assembly of metallic centres and bridging organic linkers. In this critical review, we review the key advances in the field and discuss the relationship between the nature and structure of specifically designed organic linkers and the properties of the products. Practical examples demonstrate that the physical and chemical properties of the linkers play a decisive role in the properties of novel functional MOFs. We focus on target materials suitable for the storage of hydrogen and methane, sequestration of carbon dioxide, gas separation, heterogeneous catalysis and as magnetic and photoluminescent materials capable of both metal- and ligand-centred emission, ion exchangers and molecular sieves. The advantages of highly active discrete complexes as metal-bearing ligands in the construction of MOFs are also briefly reviewed (128 references).

Patrícia SilvaJoão RochaMicrowave heating, used in organic chemistry for several decades, has only recently been applied to the preparation of multi-dimensional coordination polymers, more commonly known as metal–organic frameworks (MOFs). Microwave heating allows short reaction times, fast kinetics of crystal nucleation and growth, and high yields of desirable products which can be isolated with few or no secondary products. The most significant developments in the use of microwave heating for the preparation of MOFs are briefly reviewed from this perspective, emphasizing systematic studies of well-characterised materials, which lead to their isolation in large quantities over economically-viable periods of time. Emphasis is given to the growth of nano-sized crystallites which may find direct applications in functional devices.

João Rocha, a Full Professor of Chemistry, served as the Director of the University of Aveiro Institute of Materials-CICECO from 2002 to 2021. He earned his PhD in Chemistry in 1990 and completed a postdoc in 1991, both at the University of Cambridge, UK. He has received several prestigious honors, including Officer of the Chemistry Division of the European Academy of Sciences-EURASC (2014), member of the Académie Royal de Belgique des Science, des Lettres et des Beaux-Arts (2022) and of the Lisbon Academy of Sciences (2006), and Fellow of the Royal Society of Chemistry (2016). He has also received awards from the Portuguese, Spanish, and French Chemical Societies. Additionally, he has served as coordinator of the ERC Consolidator Grants panel PE11. Rocha has published about 550 SCI papers and 5 patents, that received (GS) over 30,000 citations (h 82). His work has significantly impacted various domains, including materials science and solid-state NMR spectroscopy. Notably, he has pioneered the creation of new materials akin to zeolites and the development of luminescent lanthanide-bearing metal–organic frameworks. Rocha has contributed substantially to the academic community, holding various editorial and advisory roles and nurturing future generations of scientists through mentoring and teaching.
