Electrolyte effects on the cationic micelle catalyzed decarboxylation of 6-nitrobenzisoxazole-3-carboxylate anion
(1973)
The unimolecular decarboxylation of 6-nitrobenzisoxazole-3-carboxylate ion is strongly catalyzed by micelles of cationic and nonionic surfactants. The catalysis by cationic micelles can be enhanced by adding some electrolytes ...
Photochromic Solid Materials Based on Poly(decylviologen) Complexed with Alginate and Poly(sodium 4-styrenesulfonate)
(2015)
Photochromic solid materials based on the cationic polymer poly(decylviologen) are reported. The solids were obtained by freeze-drying colloidal suspensions of nanocomplexes obtained by mixing aqueous solutions of the ...
Aggregation phenomena in photobicyclised pyridinium salts
(Royal Society Chemistry, 2017)
The possible formation of aggregates in a solution of two planar heterocyclic salts, 2-phenylbenzo[8,9]quinolizino[ 4,5,6,7-fed] phenanthridinylium tetrafluoroborate (PQPBF(4)) and thienyl-substituted 2-phenylbenzo[ij]py ...
Interação entre líquidos iônicos mono e dicatiônicos derivados do imidazolíneo e metilcelulose em solução aquosa e estado gel
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2016-07-28)
This paper describes the interactions between methylcellulose (MC) with a serie of imidazolium ionic liquids (LIs) monocationic (CnMIMBr) and its similar dicationic (Cn(MIM)2Br2) in a aqueous enviroment. The effect of the ...
Complexation of amino sugars with cobalt(III) bis (phenanthroline)
(Elsevier, 1998)
The I3- salts soluble in acetone and sparingly so in methanol, and I3- inhibits formation of Co(II) so that minor decomposition of acomplex does not broaden its 1H NMR signals. The (phen)2 complex of Co(III) with D-glucosamine ...
Formation and structure of a complex of sucrose with cobalt(III)bis(phenanthroline)
(ELSEVIER SCI LTD, THE BOULEVARD, 2001-07-12)
Sucrose forms a dicationic complex with cobalt(III)bis(phenanthroline) which can be isolated as the sparingly water-soluble triiodide salt or the water-soluble chloride. The circular dichroism (CD) spectrum demonstrates ...
Preparation of new cationic complexes [(η5-C5H5)Fe(dppe)L]PF6 with sulphur and other donor ligands
(1994)
The reaction of (η5-C5H5)Fe(dppe)I with the ligand L′ (L′ = S2(CH3)2, C6H5SNR2 (R = CH3, C6H11), S(NC4H8O)2, P(n-Bu)3, tetrahydrofuran and NC5H5 in the presence of T1PF6 have been investigated. Formation of the new cationic ...
Synthesis, characterization and application of a hexagonal mesoporous silica for pesticide removal from aqueous solution
(Elsevier Science Inc, 2014-03)
A hexagonal mesoporous silica (SiO2) was hydrothermally synthesized in alkaline media by using mixed cationic cetyltrimethylammonium tosylate-non-ionic Pluronic F68 surfactants as template. After characterization by commonly ...
