Prussian blue analogues of reduced dimensionality.
Mixed-valence polycyanides (Prussian Blue analogues) possess a rich palette of properties spanning from room-temperature ferromagnetism to zero thermal expansion, which can be tuned by chemical modifications or the application of external stimuli (temperature, pressure, light irradiation). While molecule-based materials can combine physical and chemical properties associated with molecular-scal...
متن کاملSynthesis and Structure of Prussian Blue Analogues
The Electrochemical Society Interface • Fall 2002 olecular magnetism is an evolving discipline relying on quantum chemistry, orbitals and Hamiltonians, organic and coordination chemistries, physics, and devices. Among the exciting molecule-based magnetic systems, Prussian blue analogues occupy a peculiar position. Prussian blue itself was described for the first time in 1704. Since this time, t...
متن کاملVacancy-driven magnetocaloric effect in Prussian blue analogues
We experimentally show that the magnetocaloric properties of molecule-based Prussian blue analogues can be adjusted by controlling during the synthesis the amount of intrinsic vacancies. For CsxNi II 4 [Cr (CN)6](8+x)/3, we find indeed that the ferromagnetic phase transition induces significantly large magnetic entropy changes, whose maxima shift from∼ 68 K to∼ 95 K by varying the number of [Cr...
متن کاملTowards bottom-up nanopatterning of Prussian blue analogues
Ordered nanoperforated TiO2 monolayers fabricated through sol-gel chemistry were used to grow isolated particles of Prussian blue analogues (PBA). The elaboration of the TiO2/CoFe PBA nanocomposites involves five steps. The samples were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), infrared spectroscopy and X-ray photoelectron spectroscopy (XPS) all along t...
متن کاملNew Magnetic Functionalities Presented by Prussian Blue Analogues
The Electrochemical Society Interface • Fall 2002 olecular magnetism has been one of the active areas in molecular chemistry for the last 15 years.1-6 The advantages of molecule-based magnets compared to classical metal and metal oxide ones are that the magnets can be obtained through a selection of proper spin sources (e.g., transition metal ions, organic radicals) and coordinating ligands. On...
