Rise of Conjugated Poly-ynes and Poly(Metalla-ynes): From Design Through Synthesis to Structure–Property Relationships and Applications

“…Molecular magnets, a term used to define discrete molecular entities exhibiting magnetic phenomena under certain conditions, have garnered a great deal of interest due to their lightweight, transparency, and magneto-optical properties. 804,805 Following the report on the magnetic properties of [(Me 3 tacn)Cr(CCH) 3 ], 296 several studies have been undertaken to delineate the magnetism in transition metal acetylide complexes 301,310,806−808 as they have potential to be used as a component for nanoscale information storage. 458,459 The magnetic property of such complexes depends on several factors: the type of ligand, the type and orientation of metal center, counterions, position of alkynyl linkage and nature of the conjugated spacer, etc.…”

Metal–Organic Framework Magnets

“…In contrast, molecule-based magnets possess high synthetic programmability and tunability. In particular, this molecule-based approach has afforded single molecules, one-dimensional (1D) chains, two-dimensional (2D) layered materials, and three-dimensional (3D) networks possessing unique magnetic behavior. ,− Moreover, some of these compounds have demonstrated fascinating multifunctional properties, , including coexistent long-range magnetic order and electrical conductivity. − In addition, the low density of molecule-based magnets may enable their application as lightweight permanent magnets for electrical devices and energy technologies. Despite the many potential advantages of molecule-based magnets over traditional solid-state inorganic magnets, a vast majority of molecule-based magnets suffer from low operating temperatures, and thus, an active focus of research in this area involves increasing the strength of magnetic exchange interactions between spin centers to realize the implementation of these and similar magnet materials in practical applications.…”
