Journal ArticleDOI
Light‐Induced Stored Information in Nanoparticles
TL;DR: In this article, the effect of particle size reduction on light-induced and thermally induced spin crossover (SCO) properties was investigated with three samples with distinct particle sizes of the SCO coordination polymer [Fe(NCS) 2 (bpe) 2 ] [bpe = 1,2-bis(4'-pyridyl)ethane] using reverse micelle methods.
Journal ArticleDOI
Atypical photomagnetic properties in a series of binuclear iron(II) spin crossover complexes
TL;DR: In this paper, the photomagnetic properties of a series of binuclear iron(II) complexes of formula [{Fe(L)(NCX)2}2bpym], where L is bpym = 2,2′-bipyrimidine and X = S, Se, by light irradiation at 647.1-676.4 nm and at 830 nm, were examined.
Journal ArticleDOI
Complexation of 2,6‐Bis(3‐pyrazolyl)pyridine–Bis(thiocyanato)iron(II) with a Bridging 4,4′‐Bipyridine: A New Example of a Dinuclear Spin Crossover Complex
Dalila Fedaoui,Dalila Fedaoui,Yacine Bouhadja,Abdellah Kaiba,Philippe Guionneau,Jean-François Létard,Patrick Rosa +6 more
TL;DR: In this paper, the coordination behavior of 2,6-bis(3-pyrazolyl)pyridine-bis (thiocyanato)iron(II) towards bridging ligands led to the discovery of a novel dinuclear complex showing spin-crossover.
Journal ArticleDOI
Structure, magnetism and photomagnetism of mixed-ligand tris(pyrazolyl)methane iron(II) spin crossover compounds
Boujemaa Moubaraki,Benjamin Aldo Leita,Gregory J. Halder,Stuart Robert Batten,Paul Jensen,Jonathan Paul Smith,John D. Cashion,Cameron J. Kepert,Jean-François Létard,Keith S. Murray +9 more
TL;DR: A range of bis-facial tridentate chelate complexes of type Fe(ii) d(6) has been characterised that contain two different tris-pyrazolylmethane ligands, with variations in R being H (complex crystallised as polymorphs and ) and 4-Me (), as well as R = H with a CH(2)OH arm off the methane carbon ().
Journal ArticleDOI
Anion doping as a probe of cooperativity in the molecular spin-crossover compound [FeL2][BF4]2 (L = 2,6-di{pyrazol-1-yl}pyridine)
TL;DR: Results suggest that cooperativity in this material is transmitted within the terpyridine embrace layers, and weakening of intermolecular pi-pi interactions between cations is the likely reason for the reduced enthalpy of spin-crossover as x increases.
