Synthesis 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 کاملGreen and efficient synthesis of propargylamines via A3 coupling reaction using a copper (II)–thioamide combination
A one pot green three‐component coupling reaction of aldehyde, phenylacetylene, and amine derivatives in the presence of copper (II)–thioamide combination as a novel and efficient heterogeneous catalyst under solvent–free conditions is reported. The catalyst displayed high activity and afforded the corresponding propargylamines in good to high yields. The key to this procedure was the generatio...
متن کاملPrussian 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 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 کاملTunable synthesis of Prussian Blue in exponentially growing polyelectrolyte multilayer films.
Polyelectrolyte multilayer (PEM) films have become very popular for surface functionalization and the design of functional architectures such as hollow polyelectrolyte capsules. It is known that properties such as permeability to small ionic solutes are strongly dependent on the buildup regime of the PEM films. This permeability can be modified by tuning the ionization degree of the polycations...
