Platinum Complexes with a Phosphino-Oxime/Oximate Ligand [PDF]

open access: yes, 2018
The platinum(II) complex [PtCl2(COD)] (2; COD = 1,5- cyclooctadiene) reacted with 1 and 2 equiv. of 2-(diphenylphosphanyl) benzaldehyde oxime (1) to generate [PtCl2{¿2-(P,N)-2- Ph2PC6H4CH=NOH}] (3) and [Pt{¿2-(P,N)-2-Ph2PC6H4CH=NOH}2]- [Cl]2 (4 ...

Melting of hexane monolayers adsorbed on graphite: the role of domains and defect formation [PDF]

open access: yesLangmuir Letters 25, 6596-6598 (2009), 2009
We present the first large-scale molecular dynamics simulations of hexane on graphite that completely reproduces all experimental features of the melting transition. The canonical ensemble simulations required and used the most realistic model of the system: (i) fully atomistic representation of hexane; (ii) explicit site-by-site interaction with ...

Simulations of the Chain Length Dependence of the Melting Mechanism in Short-Chained n-alkane Monolayers on Graphite [PDF]

open access: yesSurface Science, vol. 600, pp. 921-932 (2006), 2005
The melting transition in solid monolayers of a series of short-chained n-alkanes, n-octane (n-C8H18), n-decane (n-C10H22), and n-dodecane (n-C12H26) physisorbed onto the graphite basal plane are studied through use of molecular dynamics simulations.

Silicon‐carbon hybrid [2]‐ladderanes [PDF]

open access: yes, 2022
The first silicon-carbon hybrid ladderanes consisting of trisila and tricarba ladder rails were obtained by the reactions of lithium disilenide R2Si=SiRLi (R=2,4,6-triisopropylphenyl) with allylchlorosilanes. The steric strain in the 1,2,6-trisilabicyclo[

Nanoscale Liquid Crystal Lubrication Controlled by Surface Structure and Film Composition [PDF]

open access: yesPhys. Chem. Chem. Phys., 2018,20, 18737-18743, 2018
Liquid crystals have emerged as potential candidates for next-generation lubricants due to their tendency to exhibit long-range ordering. Here, we construct a full atomistic model of 4-cyano-4-hexylbiphenyl (6CB) nematic liquid crystal lubricants mixed with hexane and confined by mica surfaces. We explore the effect of the surface structure of mica, as

[μ-1,3-Dioxo-1,3-bis(pyridin-2-yl)propane-2,2-diido-κ2N,C2:κ2C2,N′]bis[(1,3-diphenylpropane-1,3-dionato-κ2O,O′)palladium(II)](Pd—Pd)

open access: yesActa Crystallographica Section E, 2011
The title compound, [Pd2(C13H8N2O2)(C15H11O2)2], crystallized from a mixture of ethanol and n-hexanes. The structure is the first example of β-diketonate in a dianionic κ2C-coordination complex containing a PdII—PdII bond ...

Diacetylene bridged triphenylamines as hole transport materials for solid state dye sensitized solar cells [PDF]

open access: yes, 2013
We have synthesized and characterized a series of triphenylamine-based hole-transport materials (HTMs), and studied their function in solid-state dye sensitized solar cells (ss-DSSCs). By increasing the electron-donating strength of functional groups (-H

Simulated Effects of Odd-Alkane Impurities in a Hexane Monolayer on Graphite [PDF]

open access: yes, 2005
We present the results of molecular dynamics simulations of odd alkane impurities present within the hexane (even alkane) monolayer. We simulate various temperatures at ca. 3%, 5%, 10%, and 15% impurities of propane, pentane, heptane, nonane, and undecane, each having a low-temperature solid phase belonging to a different space group as compared to ...
