Self-Assembly, Structures, Magnetic Properties and Solution Behaviors of Six Mixed-Valence Cobalt Clusters

13-Sep-2017 | Yunwu Li; Ling-Yu Guo; Lei Feng; Zvonko Jaglicic; Suyuan Zeng; Di Sun, CrystEngComm, 2017

The introduction of multidentate chelating ligands and secondary small inorganic anions into variable valence cobalt synthesis system led to the formation of six novel mixed-valence cobalt clusters, namely, [CoII2CoIII2(mdea)2(OH)2(2,2’-bipy)2(CH3CN)4]•4ClO4•2H2O (SD/Co1), ...

Theoretical and experimental study of ground and excited states of 1,4-dihydropyridine based hexahydroquinoline derivatives achieved by microwave irradiation

13-Sep-2017 | Miyase Gündüz; Claudia da Silva; Gabriel Zanotto; Josene M Toldo; Rahime Simsek; Cihat Safak; Paulo F.B. G ..., New Journal of Chemistry, 2017

In this article, the photophysical characterisation in solution of a serie of hexahydroquinoline derivatives is described using UV-Vis absorption and steady-state fluorescence emission spectroscopies. The compounds were obtained from one-pot four component synthesis via Hantzsch reaction using ...

Shortwave infrared luminescent Pt-nanowires: mechanistic study of emission in solution and solid state

13-Sep-2017 | Carl Cheadle; Jessica Ratcliff; Mikhail Y. Berezin; Vadim Pal'shin; Victor Nemykin; Nikolay Gerasimchuk, Dalton Transactions, 2017

Several complexes of “PtL2” composition containing two cyanoxime ani-ons – 2-oximino-2-cyano-N-piperidineacetamide (PiPCO-) and 2-oximino-2-cyano-N-morpholylacetamide (MCO-) have been obtained and characterized both in solutions and in solid state. Complexes exist as two distinct polymorphs: ...

Translocation across a self-healing block copolymer membrane

13-Sep-2017 | Sabrina Nehache; Prashant Tyagi; Mona Semsarilar; Andre Deratani; T. N. Trang Phan; Didier Gigmes; Damien Quémener, Soft Matter, 2017

Herein, a membrane prepared from the self-assembly of poly(styrene-co-acrylonitrile)-b-poly(ethylene oxide)-b-poly(styrene-co-acrylonitrile) micelles is found to exhibit translocation of nano-objects dispersed in aqueous solution. With the water flow as a driving force, temporary pores are ...

PPh4Cl in aqueous solution – the aggregation behavior of an antagonistic salt

13-Sep-2017 | Robert Winkler; Thomas Buchecker; Florian Hastreiter; Didier Touraud; Werner Kunz, Physical Chemistry Chemical Physics, 2017

The initial definition of hydrotropy by Neuberg in 1916 describes a hydrotrope as a molecule which enhances the solubilization of hydrophobic substances in water. Sodium dodecyl sulfate (SDS) and sodium xylene sulfonate (SXS) are typical representatives fulfilling this old definition. They are ...

Dendritic Lamellar Assembly in Solution-Cast Poly(L-lactic acid) Spherulites

13-Sep-2017 | Hsin-Ping Chen; Eamor M Woo, CrystEngComm, 2017

Poly(L-lacic acid) (PLLA) interacting with solvents of different interaction strength crystallizes, upon solvent evaporation, into spherulites of various birefringence patterns. Top surface-relief morphologies in correlations with interior lamellae assembly in solvent-evaporated PLLA confined in ...

Visible light-induced C3-sulfonamidation of imidazopyridines with sulfamides

13-Sep-2017 | Yongyuan Gao; Shu Chen; Weiye Lu; Weijin Gu; Ping Liu; Peipei Sun, Organic & Biomolecular Chemistry, 2017

A visible light-induced regioselective sulfonamidation of imidazo[1,2-a]pyridines was developed by using sulfamides as the nitrogen sources and aqueous NaClO solution as the oxidant under mild conditions. For the imidazo[1,2-a]pyridines bearing various substituents, the reaction proceeded ...

Columnar bent-core liquid crystals with two oxadiazole units and two or four alkyl chains and their phase-dependent fluorescence

13-Sep-2017 | Hugo Gallardo; Marli Ferreira; Eduard Westphal; Mariana Victoria Ballottin; Ivan H Bechtold; Adailton J Bortoluzzi; ..., New Journal of Chemistry, 2017

Bent-core mesogens containing two 1,3,4-oxadiazole rings, two or four terminal alkoxy chains and a polar nitro, amino or hydroxyl substituent on the central rigid core exhibit enantiotropic hexagonal columnar mesophases and show blue fluorescence emission in solution and solid state. ...

Large n- and p-type thermoelectric power factors from doped semiconducting single-walled carbon nanotube thin films

13-Sep-2017 | Bradley A. MacLeod; Noah J. Stanton; Isaac E. Gould; Devin Wesenberg; Rachelle Ihly; Zbyslaw R. Owczarczyk; Katherin ..., Energy & Environmental Science, 2017

Lightweight, robust, and flexible single-walled carbon nanotube (SWCNT) materials can be processed inexpensively using solution-based techniques, similar to other organic semiconductors. In contrast to many semiconducting polymers, semiconducting SWCNTs (s-SWCNTs) represent unique one-dimensional ...
