Summary: Exploring the chemical space of a ligand and modulating its ligand field strength is an effective strategy for fine-tuning the physical properties of spin-crossover complexes. This computational study investigates how ligand substituent effects can modulate the transition temperature (T-1/2) in Fe(iii) SCO systems and identifies suitable descriptors for predicting these changes. The study provides insights into the design of new SCO systems with specific T-1/2 values based on ligand design.

Summary: By studying a dataset of 24 different Fe(iii) hexacoordinated complexes, it was demonstrated that the B3LYP* functional is accurate in predicting spin-state energy gaps and distinguishing spin states of Fe(iii) complexes across a range of temperatures.

Summary: This study explores the impact of electron-donating and electron-withdrawing substituents on the spin crossover behavior of Fe(III) complexes based on SalEen ligands.

Summary: At the core of carbon monoxide dehydrogenase (CODH) active site, two metal ions and hydrogen bonding from amino acids facilitate the interconversion between CO2 and CO. A designed molecular catalyst with a bimetallic iron complex and hydrogen bonding interactions showed improved selectivity and stability in heterogeneous CO2 reduction to CO. X-ray structures revealed the compromise between rigidity and flexibility of the catalyst in accommodating CO2 capture, activation, and reduction.

Summary: In this study, three new neutral Fe(II) SCO molecules belonging to the {Fe[H2B(pz)(2)](2)(L)} family were synthesized, and their crystallographic structure and magnetic properties were investigated. These compounds exhibited thermal- and light-induced SCO transitions with different degrees of cooperativity and effectiveness. Furthermore, two of the compounds were demonstrated to be sublimable, forming homogeneous thin films that retained the chemical integrity of the original molecules. SCO/2D horizontal hybrid devices based on CVD-graphene were successfully produced using these films, enabling the detection of the thermal SCO transition through the electric properties of CVD-graphene.

Summary: This article describes a tetrazine derivative that exhibits color-tunable crystals upon external stimuli. By heating and cooling processes, Bis(4-methylphenoxy)tetrazine (1) forms crystalline phases with photoluminescence color transitions ranging from green to red. These thermoresponsive polymorphisms and colors can be reversibly recovered by solvent vapor annealing. Additionally, the unique T-shape arrangement of the tetrazine rings and the phenyl rings leads to the formation of flexible crystals.

Summary: Post-synthetic modification is a powerful technique for accessing noncanonical peptide derivatives selectively, but it has not been used for installing multiple arrays of modified side chains. In this study, we applied this approach in solution phase to prepare short N- and C-capped homooligomers of 3-amino-1-methylazetidine-3-carboxylic acid with all azetidine side chain functions in the free amine form. The key step involved multiple reductive amination reactions of the corresponding post-synthetically deprotected secondary amines.

Summary: Temperature dependent X-ray photoemission spectroscopy (XPS) was used to study the spin-crossover (SCO) transition in the nanocrystals of 3D Hoffman-like {Fe(pz)[Pt(CN)(4)]}. The temperature-dependent variations in the Fe 2p core-level spectrum provide clear evidence of the spin-state transition in this SCO complex. The lack of discernible temperature-driven shifts in the binding energies of the N 1s core-level components may be due to the immunity of its HS electronic configuration to thermal fluctuations. The high-spin fraction versus temperature plot extracted from XPS measurements indicates that the surface of the nanocrystals of {Fe(pz)[Pt(CN)(4)]} is in the high-spin state at room temperature, making it promising for room-temperature spintronics and quantum information science applications.

Summary: Functionalization of spin crossover porous coordination polymers (PCPs) with hydrogen-bonding active groups is an efficient strategy for the study of multifunctional materials. The interaction of guests with the host framework can improve the cooperativity of the spin crossover (SCO) and further enhance its properties.

Summary: This work presents studies on the photochemical transformations of TU and Cys with the addition of Cu(II) or Fe(III) ions. The results show that the oxidation rate of the thiols increases significantly when Cu(II) or Fe(III) ions are added to the system. It has also been found that TU and Cys can form stable complex compounds with the studied metal ions. The oxidation rates of the thiols are found to depend on the radiation intensity and emission spectrum of the irradiation sources.

Summary: The structure and electrochemical properties of zinc(II) complexes with a face-capping ligand have been investigated, revealing the effect of the ligand on bound semiquinonate (SQ) radicals. The substitution pattern of the SQ ring plays a crucial role in determining the fate of the bound SQ radicals. Additionally, the protective pocket formed by the ligand's phenyl substituents is unable to prevent decomposition of SQ radicals with minimal steric bulk, suggesting that substitution of the SQ ring is the main contributor to their stabilization.

Summary: In this article, the synthesis and characterization of copper, nickel, and palladium complexes bound by bidentate ligands derived from ortho-phenylenediamine are described. The complexes contain tunable H-bond donors and their crystal structures reveal intramolecular H-bonding interactions between the ligand scaffolds. Variations in the coordination sphere led to the isolation of the complexes in square-planar or twisted pseudo-tetrahedral geometries. Structural analysis showed that intramolecular H-bonding interactions can be altered by disrupting the bonds between countercations, solvent of crystallization, and ligand scaffold, resulting in changes in the geometry of the complexes. DFT calculations confirmed that Cu complexes prefer twisted geometries while Ni and Pd complexes favor square-planar geometries.
