Upon adding tetrabutyl ammonium halides (fluoride, chloride bromide and iodide), cyanide and hydroxide ions to their solutions in DMSO respectively, the colour of the solutions has shown striking changes from pale yellow to brillant yellow or red. The binding effects of the anions were investigated by UV-VIS spectroscopic method and H-1 NMR titrations.eninfo:eu-repo/semantics/openAccessN-Substituted thioureaAnion coordinationUV-VIS and H-1 NMR titrationsArticle2552455245810.14233/ajchem.2013.13396Q4WOS:0003172458000232-s2.0-84875092117Q4
