Tuning the Optical Properties of Magnetic Materials

Abstract

The development of new technologies requires research on novel functional materials. In recent years, controlling the optical properties of magnetic materials has been investigated in fields such as chemistry, physics, and materials science. This brief review surveys optical property tuning in molecular magnetic materials with an emphasis on cyanido-bridged coor-[a]

Ultrafast photoinduced dynamics in Prussian blue analogues

“…It is the mixed valency and superexchange interaction through the cyanide bridge that is the source of magnetic ordering in PBAs. The advantages of PBAs include room-temperature magnetic ordering (although limited to the V-Cr PBA), 69,70 tuneability of magnetic [71][72][73][74] and optical properties, [75][76][77][78] as well as multifunctional properties such as photomagnetism [79][80][81] and electrochromism.

“…97 There are already several excellent reviews on PBAs. 67,70,77,[98][99][100] We also note a wealth of other cyano-bridged materials with very exciting photomagnetic properties. 67,101 The primary photophysical processes in molecular materials happen on the fs timescale, and so we have attempted to collate studies concerning ultrafast dynamics in PBAs (occurring on the fs/ps timescales).…”

Effects of External Field Wavelength and Solvation on the Photophysical Property and Optical Nonlinearity of 1,3-Thiazolium-5-Thiolates Mesoionic Compound

“…Therefore, the field of optical materials has been exploring how to develop new compounds with tunable photophysical properties or enhanced (hyper)polarizabilities for a long time. [4][5][6] So far, researchers have successfully recognized a variety of molecules with exciting optical properties, including inorganic complexes, [7][8][9] organic molecules, [10][11][12][13] metal clusters, 14,15 doped polarizable electrides, 16,17 and even macrocyclic compounds with special topology, 6,18,19 and applied some of them into practice. Among them, the conjugated organic chromophores with electron donating and electron accepting groups at both ends were one of the most popular optical units, partially due to their convenient structural tailoring.…”

Optically controlled large-coercivity room-temperature thin-film magnets

“…light-induced excited spin-state trapping or lightinduced metal-to-metal charge transfer. 17 The state-of-the-art photomagnetic material variety comprises e.g. Prussian blue type metal complexes, 12,18,19 as well as magnetic nanoparticles 14,20,21 and layered inorganics 16 modified with photo-responsive organic molecules.…”
