Acyclic Pseudopeptidic Hosts as Molecular Receptors and Transporters for Anions

03-Jul-2015 | Inés Martí, M. Isabel Burguete, Philip A. Gale, Santiago V. Luis, European Journal of Organic Chemistry, 2015

Abstract The synthesis and characterization of different pseudopeptidic hosts derived from open chain systems with C2 and C3 symmetry has been achieved. These receptors are based on structures containing phenylalanine amino acid residues and amine, amide, urea and thiourea groups as the ...


Post‐Assembly Stabilization of Rationally Designed DNA Crystals

02-Jul-2015 | Jiemin Zhao, Arun Richard Chandrasekaran, Qian Li, Xiang Li, Ruojie Sha, Nadrian C. Seeman, Chengde Mao, Angewandte Chemie International Edition, 2015

Abstract This manuscript reports an effort to stabilize self‐assembled DNA crystals. Owing to their weak inter‐unit cohesion, self‐assembled DNA crystals are fragile, which limits the potential applications of such crystals. To overcome this problem, another molecule was introduced, which ...


Naked Eye Instant Reversible Sensing of Cu2+ and Its In-Situ Imaging in Live Brine Shrimp Artemia

01-Jul-2015 | Ratish R Nair; M Raju; Neha M Patel; Ishan H Raval; Suresh Eringathodi; Soumya Haldar; Pabitra Baran Chatterjee, Analyst, 2015

A Cu2+-specific colorimetric reversible fluorescent receptor HL was designed and synthesized which showed naked eye observable colour change from colourless to pink on addition of aqueous buffer (pH 7.4) solution of 30 ppb Cu2+. Short response time (≤ 5 sec) and low detection limit (nearly 3 ppb) ...


Carbon Monoxide Addition Reaction of a Ru Dithiolene Complex and polysiloxane Hybrid Film Formation

30-Jun-2015 | Satoru Tsukada, Takuya Sagawa, Takahiro Gunji, Chemistry - An Asian Journal, 2015

Carbon monoxide addition reaction on the ruthenium center of [(η‐CMe)Ru(SCH)] (1) is investigated. [(η‐CMe)Ru(CO)(SCH)] (2) was obtained by the addition of CO gas to the ruthenium center of 1 in both solution and solid states. 1 was reproduced by the reaction of 2 with oxidant. A 1/polysiloxane ...


A Comparative Study of [CaEDTA]2– and [MgEDTA]2–: Structural and Dynamical Insights from Quantum Mechanical Charge Field Molecular Dynamics

30-Jun-2015 | Andreas O. Tirler; Thomas S. Hofer, Journal of Physical Chemistry B, 2015

Structure and dynamics of [MgEDTA]2– and [CaEDTA]2– complexes in aqueous solution have been investigated via quantum mechanical/molecular mechanical (QM/MM) simulations. While for the first a 6-fold octahedral complex has been observed, the presence of an additional coordinating water ligand has ...


Water Activity Measurements by the Isopiestic Method for the MCl–CaCl2–H2O (M = Na, K) Systems at 323.15 K

30-Jun-2015 | Haijun Han; Lijiang Guo; Dongdong Li; Ouyang Dong; Yan Yao; Ning Zhang; Dewen Zeng, Journal of Chemical & Engineering Data, 2015

In this work, the water activities of the NaCl–CaCl2–H2O and KCl–CaCl2–H2O ternary systems and of their sub-binary systems NaCl–H2O and KCl–H2O were measured using an isopiestic method at 323.15 K. The isopiestic composition line for the NaCl–CaCl2–H2O system was found to obey the Zdanovskii rule ...


Micelle Formation in Liquid Ammonia

30-Jun-2015 | Joseph M. Griffin; John H. Atherton; Michael I. Page, The Journal of Organic Chemistry, 2015

Perfluorinated long chain alkyl amides aggregate in liquid ammonia with increasing concentration which reflects micelle-type formation based on changes in 19F NMR chemical shifts. The critical micelle concentrations (cmc) decrease with increasing chain length and give Kleven parameters A = 0.18 ...


Experimental survey of the kinetics of acene Diels–Alder reactions

26-Jun-2015 | Brittni A. Qualizza, Jacob W. Ciszek, Journal of Physical Organic Chemistry, 2015

Second‐order rate constants were gathered for solution Diels–Alder reactions of substituted and unsubstituted acenes, with the intention of ascertaining ideal diene–dienophile combinations. Particular focus was placed on the larger ring systems namely tetracene, pentacene, and rubrene. The rate ...


Effects of Ce on inclusions and corrosion resistance of low‐nickel austenite stainless steel

26-Jun-2015 | G.‐J. Cai, C.‐S. Li, Materials and Corrosion, 2015

Effects of Ce on the corrosion resistance of low‐nickel austenite stainless steel containing Ce from 0.005 to 0.022 wt% were investigated in 3.5 wt% NaCl solution, 5 wt% H2SO4 solution, 1 mol/L NaHCO3 and 0.5 mol/L Na2CO3 solution. The results demonstrate that addition of Ce to low‐nickel ...
