Interlayer Interaction of Two-Dimensional Layered Spin Crossover Complexes [Fe^IIH₃L^Me][Fe^IIL^Me]X (X^- = ClO₄^-, BF₄^-, PF₆^-, AsF₆^-, and SbF₆^-; H₃L^Me = Tris[2-(((2-methylimidazol-4-yl)methylidene)amino)ethyl]amine)

A series of two-dimensional (2D) spin crossover complexes, [FeIIH3LMe][FeIILMe]X (X- = ClO4-, BF4-, PF6-, AsF6-, SbF6-) 1−5, have been synthesized, where H3LMe denotes an hexadentate N6 tripodlike ligand containing three imidazole groups, tris[2-(((2-methylimidazol-4-yl)methylidene)amino)ethyl]amine. Compounds 1−5 exhibit a two-step (HS-[FeIIH3LMe]2+ + HS-[FeIILMe]-) ↔ (HS-[FeIIH3LMe]2+ + LS-[FeIILMe]-) ↔ (LS-[FeIIH3LMe]2+ + LS-[FeIILMe]-) spin-transition. The crystal structure of [FeIIH3LMe][FeIILMe]PF6 (3) was determined at 295, 200, and 100 K. The structure consists of homochiral extended 2D puckered sheets, in which the complementary [FeIIH3LMe]2+ and [FeIILMe]- capped tripodlike components, linked together by imidazole−imidazolate hydrogen bonds, are alternately arrayed in an up-and-down mode. The Fe−N bond distances and angles revealed that the FeII sites of both constituting units are in the high-spin (HS) state at 295 K; at 200 K, the FeII sites of [FeIIH3LMe]2+ and [FeIILMe]- are in the HS and low-spin (LS) states, respectively. The FeII sites of both constituting units are in the LS state at 100 K. The size of the counteranion affects significantly the intra- and interlayer interactions leading to modifications of the spin crossover behavior. The onset of the second spin-transition of the ClO4- (1) and BF4- (2) salts adjoins the first spin-transition, while a mixed (HS-[FeIIH3LMe]2+ + LS-[FeIILMe]-) spin-state spans a temperature range as wide as 70 K for salts 3−5 with larger counteranions, PF6-, AsF6-, and SbF6-, respectively. Compounds 1 and 2 showed remarkable LIESST (light induced excited spin state trapping) and reverse-LIESST effects, whereas 3−5 showed no remarkable LIESST effect. The interlayer interaction due to the size of the counteranion is an important factor governing the spin crossover behavior and LIESST effect

A 2D Layered Spin Crossover Complex Constructed by NH···Cl^- Hydrogen Bonds: [Fe^IIH₃L^Me]Cl·I₃ (H₃L^Me = Tris[2-(((2-methylimidazoyl-4-yl)methylidene)amino)ethyl]amine

A 2D layered spin crossover complex, [FeIIH3LMe]Cl·I3, has been synthesized from the reaction of FeIIICl3, a tripod ligand (H3LMe = tris[2-(((2-methylimidazoyl-4-yl)methylidene)amino)ethyl]amine), and NaI in methanol. The compound showed an abrupt spin transition between the HS (S = 2) and LS (S = 0) states at T1/2 = 110 K without hysteresis. The crystal structures of the HS and LS states were determined at 180 and 90 K. A 2D layered structure is composed of NH···Cl- hydrogen bonds between the Cl- ion and three neighboring imidazole groups of [FeIIH3LMe]2+. The green light irradiation at 5 K induced the LIESST effect, and the thermal relaxation process from the HS to LS state showed a sigmoid curve at T > 55 K

A New Family of Spin Crossover Complexes with a Tripod Ligand Containing Three Imidazoles: Synthesis, Characterization, and Magnetic Properties of [Fe^IIH₃L^Me](NO₃)₂·1.5H₂O, [Fe^IIIL^Me]·3.5H₂O, [Fe^IIH₃L^Me][Fe^IIL^Me]NO₃, and [Fe^IIH₃L^Me][Fe^IIIL^Me](NO₃)₂ (H₃L^Me = Tris[2-(((2-methylimidazol-4-yl)methylidene)amino)ethyl]amine)

A new family of spin crossover complexes, [FeIIH3LMe](NO3)2·1.5H2O (1), [FeIIILMe]·3.5H2O (2), [FeIIH3LMe][FeIILMe]NO3 (3), and [FeIIH3LMe][FeIIILMe](NO3)2 (4), has been synthesized and characterized, where H3LMe denotes a hexadentate N6 tripod ligand containing three imidazole groups, tris[2-(((2-methylimidazol-4-yl)methylidene)amino)ethyl]amine. It was found that the spin and oxidation states of the iron complexes with this tripod ligand are tuned by the degree of deprotonation of the imidazole groups and by the 2-methyl imidazole substituent. Magnetic susceptibility and Mössbauer studies revealed that 1 is an HS-FeII complex, 2 exhibits a spin equilibrium between HS and LS-FeIII, 3 exhibits a two-step spin transition, where the component [FeIILMe]- with the deprotonated ligand participates in the spin transition process in the higher temperature range and the component [FeIIH3LMe]2+ with the neutral ligand participates in the spin transition process in the lower temperature range, and 4 exhibits spin transition of both the FeII and FeIII sites. The crystal structure of 3 consists of homochiral extended 2D puckered sheets, in which the capped tripodlike components [FeIIH3LMe]2+ and [FeIILMe]- are alternately arrayed in an up-and-down mode and are linked by the imidazole−imidazolate hydrogen bonds. Furthermore, the adjacent 2D homochiral sheets are stacked in the crystal lattice yielding a conglomerate as confirmed by the enantiomeric circular dichorism spectra. Compounds 3 and 4 showed the LIESST (light induced excited spin state trapping) and reverse-LIESST effects upon irradiation with green and red light, respectively

Titanium Nanosurface with a Biomimetic Physical Microenvironment to Induce Endogenous Regeneration of the Periodontium

The periodontium supports the teeth by dentoalveolar fibrous joints that serve unique oral functions. Endogenous regeneration of the periodontium around artificial teeth (dental implants) provides a cost-effective solution for the extension of healthy life expectancy but remains a challenge in regenerative medicine. Biomimetics can create smart biomaterials that tune endogenous cells at a tissue–material interface. Here, we created a smart titanium nanosurface mimicking the surface nanotopography and micromechanical properties of the tooth root cementum (TRC), which is essential for the induction of dentoalveolar fibrous joints to regenerate the periodontium. After transplantation into the rat renal capsule, only the titanium artificial tooth with the TRC-mimetic nanosurface formed a complex dentoalveolar fibrous joint structure, with bone tissue, periodontal ligament (PDL), and TRC, in the decellularized jawbone matrix. TRC-mimetic titanium implants induce the formation of functional periodontium, even in a jawbone implantation model, which generally causes osseointegration (ankyloses). In human PDL cells, TRC analogousness in the surface mechanical microenvironment regulates matrix mineralization through bone sialoprotein expression and phosphorus metabolism, which are critical for cementogenesis. Therefore, the titanium nanosurfaces with nanotopographical and mechanical microenvironments mimicking the TRC surface induce dentoalveolar fibrous joints for periodontal regeneration by interfacial tuning of endogenous cells
