Hierarchical helicates based on ketone-substituted titanium(IV)triscatecholates show different monomer-dimer behavior depending on different solvents. The dimerization constants of a whole series of differently alkyl-substituted complexes is analyzed to show that the solvent has a very strong influence on the dimerization. Hereby, effects like solvophobicity/philicity, sterics, electronics of the substituents and weak side-chain-side-chain interactions seem to act in concert.

Solvatochromism and cis-trans isomerism in azobenzene-4-sulfonyl chloride.

Photochem Photobiol Sci

January 2025

CQC-IMS, Department of Chemistry, University of Coimbra, 3004-535, Coimbra, Portugal.

Solvatochromism exhibited by azobenzene-4-sulfonyl chloride (here abbreviated as Azo-SCl) has been investigated in a series of non-polar, polar-aprotic and polar-protic solvents. The UV-vis spectra of Azo-SCl exhibit two long-wavelength bands, observed at 321-330 nm (band-I) and 435-461 nm (band-II), which are ascribed to the π*-π (S ← S) and π*-n (S ← S) transitions, respectively. The shorter wavelength band indicates a reversal in solvatochromism, from negative to positive solvatochromism, for a solvent with a dielectric constant of 32.

Growth of Hexagonal Boron Nitride from Molten Nickel Solutions: A Reactive Molecular Dynamics Study.

ACS Appl Mater Interfaces

January 2025

Department of Anatomy and Physiology, Kansas State University, Manhattan, Kansas 66506, United States.

Metal flux methods are excellent for synthesizing high-quality hexagonal boron nitride (hBN) crystals, but the atomic mechanisms of hBN nucleation and growth in these systems are poorly understood and difficult to probe experimentally. Here, we harness classical reactive molecular dynamics (ReaxFF) to unravel the mechanisms of hBN synthesis from liquid nickel solvent over time scales up to 30 ns. These simulations mimic experimental conditions by including relatively large liquid nickel slabs containing dissolved boron and a molecular nitrogen gas phase.

Excited-State Proton Transfer Dynamics of Cyanonaphthol in Protic Ionic Liquids: Concerted Effects of Basicity of Anions and Alkyl Carbons in Cations.

J Phys Chem B

January 2025

Department of Applied Chemistry, Graduate School of Science and Engineering, Doshisha University, Kyotanabe, Kyoyo 610-0321, Japan.

Excited-state proton transfer (ESPT) reactions of 5-cyano-2-naphthol (5CN2) and 5,8-dicyano-2-naphthol (DCN2) were investigated in protic ionic liquids (PILs) composed of quaternary ammonium (NH) ( = 2, 4, or 8) and hexanoate (CHCOO) using time-resolved fluorescence spectroscopy. The effects of the number of alkyl carbons in the cation and the basicity of the anion on the reaction yield and dynamics were examined. In a series of [NH][CHCOO], fluorescence from the hydrogen-bonding complex (AHBX) of a proton-dissociated form (RO) with a solvent acid in the electronic excited state was observed between the fluorescence bands of an acidic form (ROH) and an anionic form (RO) as in the case of [NH][CFCOO] (Fujii et al.

Finding of new environmentally friendly cellulose solvent system is critical for efficient usage of cellulose. In this paper, cellulose solvent based on the mixture of di-tetrabutylammonium hydrogen phosphate and dimethyl sulfoxide (TBAHPO/DMSO) was developed. We found that TBAHPO/DMSO system has excellent solubility of cellulose.
