Solution and solid-phase halogen and C–H hydrogen bonding to perrhenate

06-Jan-2015 | Casey J. Massena; Asia Marie S. Riel; George F. Neuhaus; Daniel A. Decato; Orion B. Berryman, Chemical Communication, 2015

1H NMR spectroscopic and X-ray crystallographic investigations of a 1,3-bis(4-ethynyl-3-iodopyridinium)benzene scaffold with perrhenate reveal strong halogen bonding in solution, and bidentate association in the solid state. A nearly isostructural host molecule demonstrates significant C–H ...

Efficient photoinduced In situ preparation of clay/poly(glycidyl methacrylate) nanocomposites using hydrogen‐donor silane

31-Dec-2014 | Khouloud Jlassi, Mémia Benna‐Zayani, Mohamed M. Chehimi, Yusuf Yagci, Journal of Polymer Science Part A: Polymer Chemistry, 2014

ABSTRACT Clay/poly(glycidyl methacrylate) nanocomposites (clay/PGMA) were prepared by in situ radical photopolymerization using N,N‐dimethylaminopropyltrimethoxysilane(DMA)‐modified bentonite clay acting as hydrogen donor for benzophenone in solution. This initiating system permits to ...

A Label-Free Fluorescence Sensing Approach for Selective and Sensitive Detection of 2,4,6-Trinitrophenol (TNP) in Aqueous Solution Using Graphitic Carbon Nitride Nanosheets

30-Dec-2014 | Mingcong Rong; Liping Lin; Xinhong Song; Tingting Zhao; Yunxin Zhong; Jiawei Yan; Yiru Wang; Xi Chen, Analytical Chemistry, 2014

An effective and facile fluorescence sensing approach for the determination of 2,4,6-trinitrophenol (TNP) using the chemically oxidized and liquid exfoliated graphitic carbon nitride (g-C3N4) nanosheets was developed. The strong inner filter effect and molecular interactions (electrostatic, π–π, ...

Bicomponent H-Bonded Porous Molecular Networks at the Liquid–Solid Interface: What Is the Influence of Preorganization in Solution?

29-Dec-2014 | Tibor Kudernac; Amal Kumar Mandal; Jurriaan Huskens, Langmuir, 2014

Tailoring the architecture of porous two-dimensional networks formed by molecules is essential for developing functional materials with low dimensionality. Here we present bicomponent porous networks with tunable pore-sizes that were formed by self-assembly of hydrogen-bonding molecules at the ...

Monomer–Dimer Divergent Behavior toward DNA in a Half-Sandwich Ruthenium(II) Aqua Complex. Antiproliferative Biphasic Activity

29-Dec-2014 | Natalia Busto; Marta Martínez-Alonso; José M. Leal; Ana M. Rodríguez; Fernando Domínguez; Ma Isabel Acuña; Gustavo E ..., Organometallics, 2014

The complex [(η6-p-cymene)Ru(OH2)(κ2-N,N-HL1)](OTf)2 (HL1 = 2-pyridin-2-yl-1H-benzimidazole), [2c](OTf)2, undergoes easy deprotonation of the N–H group at physiological pH, producing [(η6-p-cymene)Ru(OH2)(κ2-N,N-L1)]+, [2c′]+, prone to dimerization both in solution and in the solid state. X-ray ...

Materials, Vol. 8, Pages 96-116: Adsorption of C.I. Natural Red 4 onto Spongin Skeleton of Marine Demosponge

29-Dec-2014 | Norman, Małgorzata ; Bartczak, Przemysław ; Zdarta, Jakub ; Tylus, Włodzimierz ; Szatkowski, Tomasz ; Stelling, Alli ..., Materials, 2014

C.I. Natural Red 4 dye, also known as carmine or cochineal, was adsorbed onto the surface of spongin-based fibrous skeleton of Hippospongia communis marine demosponge for the first time. The influence of the initial concentration of dye, the contact time, and the pH of the solution on the ...

Power of a Remote Hydrogen Bond Donor: Anion Recognition and Structural Consequences Revealed by IR Spectroscopy

29-Dec-2014 | Masoud Samet; Mohammad Danesh-Yazdi; Alireza Fattahi; Steven R. Kass, The Journal of Organic Chemistry, 2014

Natural and synthetic anion receptors are extensively employed, but the structures of their bound complexes are difficult to determine in the liquid phase. Infrared spectroscopy is used in this work to characterize the solution structures of bound anion receptors for the first time, and ...

The Paradox of Hydrogen-Bonded Anion–Anion Aggregates in Oxoanions: A Fundamental Electrostatic Problem Explained in Terms of Electrophilic···Nucleophilic Interactions

26-Dec-2014 | Ignasi Mata; Elies Molins; Ibon Alkorta; Enrique Espinosa, Journal of Physical Chemistry A, 2014

A theoretical study of anionic complexes formed by two partly deprotonated oxoacids joined by hydrogen bonds has been carried out at the MP2 computational level. In spite of the ionic repulsion, local energy minima are found both in the gas phase and in aqueous solution. Electrostatic potential ...

Solution studies on DNA interactions of substitution-inert platinum complexes mediated via the phosphate clamp

25-Dec-2014 | Y. Qu; R. G. Kipping; N. P. Farrell, Dalton Transactions, 2014

The phosphate clamp is a distinct mode of ligand–DNA binding where the molecular recognition is manifested through (“non-covalent”) hydrogen-bonding from am(m)ines of polynuclear platinum complexes to the phosphate oxygens on the oligonucleotide backbone. This third mode of DNA binding is unique ...
