The correlation between the 1%-NMR chemical shift of the aromatic ring carbon bearing the leaving group and the yield of nucleophilic aromatic displacement with no-carrier-added [ 18Flfluoride ion was evaluated. In comparison of structurally analogous compounds (fluoro, nitro and trimethylammonium substituted benzaldehydes, benzophenones and benzonitriles), the 13C-NMR chemical shift of the rea...

Fullerene (C(60)), the third carbon allotrope, is a classical engineered material with the potential application in biomedicine. However, extremely high hydrophobicity of fullerene hampers its direct biomedical evaluation and application. In this work, we investigated the solubilization of fullerene using 9 different solubility enhancers: Tween 20, Tween 60, Tween 80, Triton X-100, PVP, polyoxy...

Crystal structure of zwitterionic trimethylammoniopropane sulfonate (Z1-Methyl) was determined by single-crystal X-ray diffractometry. Z1-Methyl crystallized in the monoclinic system, space group P2(1), with a = 6.3639(2), b = 10.9237(4), c = 8.1505(4) A, beta = 111.078(2) degrees, V = 528.69(4) A3, Z = 2. An inter-molecular ionic association was observed in the crystal. The shortest distance b...

Spontaneous formation of ruthenium nanochains is accomplished in aqueous medium under mild conditions using a seed mediated protocol with cetyl trimethylammonium bromide (CTAB) as the capping agent. They are formed due to the random self-assembly of Ru seeds of ∼3.5 nm size. These 1D nanostructures exhibit better catalytic activity towards the oxidation of CO relative to the ∼3.5 nm seeds and 6...

From a deep eutectic mixture consisting of trimethylammonium chloride (TMACl) and oxalic acid, two templated zirconium phosphates, ZrPOF-TMA1 with 8- and 10-ring pore channels as well as ZrPOF-TMA2 with 7- and 8-ring pore channels, have been synthesized. A low P/Zr ratio is necessary for ZrPOF-TMA1, and higher P/Zr ratios tend to form ZrPOF-TMA2, but the former cannot be obtained by templating ...
