Photoalignment at the nematic liquid crystal - polymer interface: the importance of the liquid crystalline molecular structure [PDF]
arXiv, 2020 The influence of the molecular structure of the nematic liquid crystal (NLC) on the photoalignment process at the NLC -- polymer interface has been investigated experimentally. NLCs having exclusively phenyl-, or cyclohexane rings in the rigid core, as well as NLCs containing both phenyl and cyclohexane groups have been considered.

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.
Advanced Photonics Research, EarlyView.Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Saturated and aromatic compounds of highly paraffinic oil and organic deposit
Известия Томского политехнического университета: Инжиниринг георесурсов, 2019 The urgency of the discussed issue is caused by the necessity to obtain the detailed information on the content and composition of hydrocarbons and heteroatomic components in high-paraffinic oils and the asfalto-resin-parafin deposits formed of the ...

Can the roles of polar and non-polar moieties be reversed in non-polar solvents? [PDF]
arXiv, 2020 Using thermodynamics integration, we study the solvation free energy of 18 amino acid side chain equivalents in solvents with different polarity, ranging from the most polar water to the most non-polar cyclohexane. The amino acid side chain equivalents are obtained from the 20 natural amino acids by replacing the backbone part with a hydrogen atom, and

Formation of unsaturated hydrocarbons in interstellar ice analogs by cosmic rays [PDF]
, 2012 The formation of double and triple C-C bonds from the processing of pure c-C6H12 (cyclohexane) and mixed H2O:NH3:c-C6H12 (1:0.3:0.7) ices by highly-charged, and energetic ions (219 MeV O^{7+} and 632 MeV Ni^{24+}) is studied. The experiments simulate the physical chemistry induced by medium-mass and heavy-ion cosmic rays in interstellar ices analogs ...

Advanced Photonics Research, EarlyView.A family of purinylidene based Ir(III) emitters, namely, f‐ct2a–d, are synthesized and utilized as both dopants and sensitizers in the construction of efficient purple to deep‐blue organic light‐emitting diode devices. It is very challenging to achieve highly efficient and low roll‐off purple to deep‐blue organic light‐emitting diodes (OLEDs) due to ...

Advanced Synthesis &Catalysis, EarlyView.Abstract Small and chiral secondary alcohols are sought‐after compounds that are frequently used in the synthesis of biologically active compounds. However, their stereochemically correct synthesis remains a challenge for the chemical industry. Synthetic routes are restrained by multiple steps and thus low atom efficiency.

Can Polarity-Inverted Surfactants Self-Assemble in Nonpolar Solvents [PDF]
arXiv, 2020 We investigate the self-assembly process of a surfactant with inverted polarity in water and cyclohexane using both all-atom and coarse grained hybrid particle-field molecular dynamics simulations. Unlike conventional surfactants, the molecule under study, proposed in a recent experiment, is formed by a rigid and compact hydrophobic adamantane moiety ...

Advanced Synthesis &Catalysis, EarlyView.Abstract A photocatalytic strategy for the radical alkenylation of aliphatic C(sp3)–H bonds with 2,3‐allenoate esters is described. The protocol takes place upon irradiation of the reaction mixture in the presence of the decatungstate anion, which triggers C−H cleavage in the chosen aliphatic substrates.

Viscosities of iodobenzene + n-alkane mixtures at (288.15-308.15) K. Measurements and results from models [PDF]
J. Mol. Liq. 401 (2024) 124628Kinematic viscosities were measured for iodobenzene + n-alkane mixtures at (288.15-308.15) K and atmospheric pressure. Using our previous density data, dynamic viscosities ($\eta$), deviations in absolute viscosity ($\Delta \eta$) and quantities of viscous flow were determined.
