Summary: Two new tetra-(ortho)substituted azobenzene derivatives with specific conformations and solvatochromic properties have been synthesized and characterized. The compounds exhibit attractive O-N contacts and show different absorption maxima shifts based on the solvent properties. Additionally, the compounds demonstrate high basicity and efficient complexation with metal ions in water. The rate of cis-to-trans thermal isomerization is found to decrease with increasing solvent polarity, suggesting a unique isomerization mechanism for ortho-substituted azobenzenes.

Summary: The study found that Si substitution significantly reduces magnetic properties and magnetic moment, while Fe substitution can increase the magnetic moment but with limited chemical stability. The magnetic hardness of SmCo5 is mainly determined by the Sm 4f localized orbital contribution, and Si substitution contributes to thermodynamic stability.

Summary: A series of D-pi-A type azobenzenes with a ferrocenyl/ferrocenylethynyl electron donor have been synthesized and characterized. The meta-ferrocenyl/ferrocenylethynyl azobenzenes show significantly improved photoisomerization properties compared to the para-ferrocenyl azobenzenes due to electronic communication influenced by the substitution position of the redox center. Compound 17 exhibits the highest amount of the cis form in the photostationary state and compounds 13, 15-17 show excellent fatigue resistance and reversibility during reversible isomerization cycles.

Summary: Quantitative synthesis of supramolecular polymers (SPs) was achieved using selective photocyclic aromatization reaction of poly(substituted phenylacetylene)s (CPs); The structures and properties of the resulting SPs were strongly influenced by those of the precursor CPs; By controlling the structures and properties of the CPs, SPs with desired properties, such as enantioselective permeability and supramolecular chirality, can be obtained.

Summary: The synthesis, characterization, optical and electrochemical properties, and theoretical studies of four new copper(II) complexes supported by a chiral Schiff base ligand derived from enantiomerically pure (1R,2R)-(-)-1,2-diaminocyclohexane have been reported. The complexes were prepared through a one-pot three-component reaction and characterized using various analytical techniques. The magnetic and electrochemical properties were investigated, and DFT calculations were conducted to explain the structure and properties of the complexes.

Summary: We report the synthesis, characterization, and crystal structures of three perfluoropropylated dibenzo[a,c]phenazine constitutional isomers, highlighting the role of perfluoropropyl group position in determining the crystal packing motif. X-ray crystallography and computational approaches reveal the significant impact of perfluoropropyl group position on the electrostatic potential distribution, leading to diverse molecular packing arrangements. The study shows the potential of perfluoropropylation in controlling solid-state arrangements and provides insights into the electronic properties of the molecules.

Summary: Welan, a branched polymer in the gellan family, shows good compatibility with divalent calcium ions for potential use in cement applications. Study on the influence of different divalent cations on gelling and thermal properties of Welan reveals that some cations promote favorable interactions among the chains, leading to stronger junction zones and elastic moduli. This finding is expected to broaden the utility of Welan in both food and non-food applications.
