Enhanced CO2 electroreduction efficiency through secondary coordination effects on a pincer iridium catalyst

24-Mar-2015 | Steven T. Ahn; Elizabeth A. Bielinski; Elizabeth M. Lane; Yanqiao Chen; Wesley H. Bernskoetter; Nilay Hazari; G. Tay ..., Chemical Communication, 2015

An iridium(iii) trihydride complex supported by a pincer ligand with a hydrogen bond donor in the secondary coordination sphere promotes the electrocatalytic reduction of CO2 to formate in water/acetonitrile with excellent Faradaic efficiency and low overpotential. Preliminary mechanistic ...

Ethanol induces the formation of water-permeable defects in model bilayers of skin lipids

18-Mar-2015 | R. Thind; D. W. O'Neill; A. Del Regno; R. Notman, Chemical Communication, 2015

We show that ethanol can induce the formation of water-permeable defects in model membranes of skin, providing a fresh perspective on ethanol as a membrane modulator. We rationalise our findings in terms of the chemical nature of ethanol, i.e., a combination of its hydrogen bonding propensity and ...

Conserved hydrogen bonding in tetrahydrocarbazolone derivatives: influence of solution-state assembly on crystal form nucleation

17-Mar-2015 | Robert M. Edkins; Elliott Hayden; Jonathan W. Steed; Katharina Fucke, Chemical Communication, 2015

Two tetrahydocarbazolone derivatives were found to show multiple unsolvated crystal forms. A persistent dimer motif was detected in solution by FTIR spectroscopy that is maintained in the kinetic crystal forms. Rationally introduced steric bulk induces the formation of a more stable catemeric ...

Decoloration rates of a photomerocyanine dye as a visual probe into hydrogen bonding interactions

11-Mar-2015 | Simone Ciampi; Paul K. Eggers; Naomi L. Haworth; Nadim Darwish; Pawel Wagner; Michelle L. Coote; Gordon G. Wallace; ..., Chemical Communication, 2015

We have developed a visual marker for the investigation of hydrogen bonding (HB) effects. The decoloration rate of a photochromic dye that incorporates a latent intra-molecular HB feature can be linked to the HB character of the media. Kinetic and thermodynamic parameters of this simple ...

2H [rightward arrow] 1T phase transition and hydrogen evolution activity of MoS2, MoSe2, WS2 and WSe2 strongly depends on the MX2 composition

10-Mar-2015 | Adriano Ambrosi; Zdeněk Sofer; Martin Pumera, Chemical Communication, 2015

We investigate herein the four most widely considered TMD materials: MoS2, MoSe2, WS2 and WSe2. A 2H → 1T phase transition occurs during the chemical exfoliation with different efficiencies among the four materials.

Role of hydrogen-bonding and its interplay with octahedral tilting in CH3NH3PbI3

10-Mar-2015 | Jung-Hoon Lee; Nick Bristowe; Paul Bristowe; Tony Cheetham, Chemical Communication, 2015

First principles calculations on the hybrid perovskite CH3NH3PbI3 predict strong hydrogen-bonding which influences the structure and dynamics of the methylammonium cation and reveal its interaction with the tilting of the PbI6 octahedra. The calculated atomic coordinates are in excellent ...

Efficient Asymmetric Transfer Hydrogenation of Ketones in Ethanol with Chiral Iridium Complexes of SpiroPAP Ligands as Catalysts

04-Mar-2015 | Wei-Peng Liu; Ming-Lei Yuan; Xiao-Hui Yang; Ke Li; jian-hua xie; Qi-Lin Zhou, Chemical Communication, 2015

A highly efficient iridium catalyzed asymmetric transfer hydrogenation of simple ketones with ethanol as a hydrogen donor has been developed. By using chiral spiro iridium catalyst (S)-1a a series of alkyl aryl ketones were hydrogenated to chiral alcohols with up to 98% ee

Building with bubbles: the formation of high surface area honeycomb-like films via hydrogen bubble templated electrodeposition

04-Mar-2015 | Blake J. Plowman; Lathe A. Jones; Suresh K. Bhargava, Chemical Communication, 2015

While the evolution of hydrogen gas is often a troublesome process accompanying electrodeposition, this feature can be exploited to template the growth of highly porous surfaces. This process, known as the dynamic hydrogen bubble template (DHBT) method, can be utilised to create a wide range of ...

A competitive amino-carboxylic hydrogen bond on a gold surface

02-Mar-2015 | Zhijing Feng; Carla Castellarin Cudia; Luca Floreano; Alberto Morgante; Giovanni Comelli; Carlo Dri; Albano Cossaro, Chemical Communication, 2015

An amino-carboxylic motif is identified as a novel synthon in the formation of 2D hetero-organic architectures at surfaces. The well-defined interacting scheme we describe herein represents an ideal prototypical system for further investigation of the interaction at surfaces of the two functional ...

Quantitative Analysis of Photons Decaying Pathways in Si Nanowires Array for High Efficient Photoelectrochemical Solar Hydrogen Generation

28-Feb-2015 | Chunyang Duan; Hui Wang; Bingchang Zhang; Fan Li; Xuemei Ou; Xiaohong Zhang, Chemical Communication, 2015

We quantitatively investigated excitons’ decaying pathways of photon-excited SiNWs array to reveal the reason for their low-performances. It is demonstrated that excitons decay through both carriers’ separation and energy transfer due to Si’s indirect-band-gap feature, and these two pathways ...
