Micellar and vesicular nanoassemblies of triazole-based amphiphilic probes triggered by mercury(II) ions in a 100% aqueous medium

22-10-2014 | Inhye Kim; Na-Eun Lee; Yoo-Jeong Jeong; Young-Ho Chung; Byoung-Ki Cho; Eunji Lee, Chemical Communication, 2014

ABA-type amphiphiles bearing a triazole-based aromatic block were easily synthesized using click chemistry, which act as fluorescent turn-off Hg2+–chemoprobes in an aqueous solution. Interestingly, the metal-binding process of amphiphiles induced nanoassemblies even below the CMCs, and the ...

Supramolecular photochemistry: from molecular crystals to water-soluble capsules

22-10-2014 | V. Ramamurthy; Shipra Gupta, Chemical Society Reviews, 2014

Photochemical and photophysical behavior of molecules in supramolecular assemblies are different and more selective than in gas and isotropic solution phases. Knowledge of the inherent electronic and steric properties of the reactant is insufficient to predict the excited state behavior of ...

Hydration of Cyanide Anion: An Ab Initio Quantum Mechanical Charge Field Molecular Dynamics Study

22-10-2014 | Syed Tarique Moin; Thomas Hofer, Physical Chemistry Chemical Physics, 2014

This paper presents an ab initio quantum mechanical charge field molecular dynamics simulation study of the cyanide anion CN- in aqueous solution where hydrogen bond formation plays a dominant role in the hydration process. Preferential orientation of water hydrogens compared to oxygen atoms was ...

The solution chemistry and reactivity of lacunary Keggin silicotungstates monitored in real-time by a combination of mass spectrometry and electrochemistry

21-10-2014 | QiaoDi Jia; Jie Cao; YunPeng Duan; Changwen Hu, Dalton Transactions, 2014

The solution chemistry of a series of mono-, di- and trilacunary Keggin silicotungstates was investigated by electrospray mass spectrometry (ESI-MS) and general electrospray features especially for lacunary POMs were summarized. The reactions of vanadium-incorporation into the lacunary structures ...

Using solution- and solid-state S K-edge X-ray absorption spectroscopy with density functional theory to evaluate M–S bonding for MS42− (M = Cr, Mo, W) dianions

21-10-2014 | Angela C. Olson; Jason M. Keith; Enrique R. Batista; Kevin S. Boland; Scott R. Daly; Stosh A. Kozimor; Molly M. MacI ..., Dalton Transactions, 2014

Herein, we have evaluated relative changes in M–S electronic structure and orbital mixing in Group 6 MS42− dianions using solid- and solution-phase S K-edge X-ray absorption spectroscopy (XAS; M = Mo, W), as well as density functional theory (DFT; M = Cr, Mo, W) and time-dependent density ...

Sol-gel deposited Cu2O and CuO thin films for photocatalytic water splitting

21-10-2014 | Yee-Fun Lim; Chin Sheng Chua; Coryl Jing Jun Lee; Dongzhi Chi, Physical Chemistry Chemical Physics, 2014

Cu2O and CuO are attractive photocatalytic materials for water splitting due to their Earth-abundance and low cost. In this paper, we report the deposition of Cu2O and CuO thin films by a sol-gel spin-coating process. Sol-gel deposition has distinctive advantages such as low-cost solution ...

Solution structure of a cucurbit[8]uril induced compact supramolecular protein dimer

21-10-2014 | Dang Dang; Ralph Bosmans; Christian Moitzi; Ilja Karina Voets; Luc Brunsveld, Organic & Biomolecular Chemistry, 2014

Supramolecular assembly of a beta-barrel protein via cucurbit[8]uril results in compact z-shaped protein dimers. SAXS data reveal the formation of a well ordered protein dimer, notwithstanding being connected by a reversible and flexible peptide linker, and highlight the supramolecular induced ...
