摘要: A new and simple phenylhydrazone-based sensor 1 for acetate has been investigated in DMSO even the 95:5 DMSO/H2O (v/v) mixtures. Binding of anions such as AcO-, F- H2PO4(-) results a noteworthy change visible region spectrum (approximately 100 nm red shift), which can be detected by 'naked-eye'. The further insights to nature interactions between AcO- were 1H NMR titration experiments DMSO-d(6). In particular, analytical application detection ion have also studied aqueous.
