Thermal- and Light-Induced Spin Crossover in a Guest-Dependent Dinuclear Iron(II) System
Jarrod J. M. Amoore,Suzanne M. Neville,Boujemaa Moubaraki,Simon S. Iremonger,Keith S. Murray,Jean-François Létard,Cameron J. Kepert +6 more
TL;DR: In this article, a two-and one-step spin crossover transition was studied for the dinuclear material [Fe(II) (2,5-di(2',2''-dipyridylamino)pyridine) and its partially desolvated analogue (1 x CH(2)Cl(2)).
Journal ArticleDOI
Ordering phenomena of high-spin/low-spin states in stepwise spin-crossover materials described by the ANNNI model
Hiroshi Watanabe,Hiroshi Watanabe,Koichiro Tanaka,Nicolas Bréfuel,Hervé Cailleau,Jean-François Létard,Sylvain Ravy,Pierre Fertey,Masamichi Nishino,Seiji Miyashita,Eric Collet +10 more
TL;DR: In this paper, the authors studied the complex spin-state switching mechanism in a bistable molecular crystal undergoing a stepwise conversion from high-spin to low-spin states at thermal equilibrium as well as during the relaxation process from the photoinduced metastable state.
Journal ArticleDOI
Quenching the Hysteresis in Single Crystals of a 1D Chain Iron(II) Spin Crossover Complex
TL;DR: In this article, the unusual grinding effects observed in the 1D spin crossover polymer [FeL(bipy)]n (1), with L being a tetradentate N2O22-coordinating Schiff base type ligand {(3,3′)-[1,2-phenylenebis(iminomethylidyne)]bis(2,4-pentanedionato)(2)-)-N,N′,O2,O 2,O
Journal ArticleDOI

TL;DR: In this article, the electronic structures of four different Fe(II) spin crossover molecules, [Fe(H2B(pz)2)2(bipy)] (pz = pyrazol-1-yl, bipy = 2,2′-bipyridine), [Fe (H 2B( pz), pz) 2(phen) 2 (phen), Fe(phen), 2,10-phenantroline), and Fe(PM-AzA)2 (NCS)2] (4-pheny
Journal ArticleDOI
Effect of metal dilution on the light-induced spin transition in [FexZn1−x(phen)2(NCS)2] (phen = 1,10-phenanthroline)
Chérif Baldé,Cédric Desplanches,Alain Wattiaux,Philippe Guionneau,Philipp Gütlich,Jean-François Létard +5 more
TL;DR: It appears that T1/2 decreases with the metal dilution while T(LIESST) remains unchanged, and this behaviour is discussed on the basis of the kinetic study governing the photo-induced back conversion.
