Chlorophyll tailored 20-trifluoroacetamide and its azacrown derivative as pH sensitive colorimetric sensor probe with response to AcO super(-), F super(-) and CN super(-) ions

Chlorophyll derivatives were functionalized with a trifluoroamide (TFA) group to obtain colorimetric ion sensors. Prior to this, a NO sub(2)BF sub(4)*pyridine based, chlorin nitration method was developed. The base strength dependent sensing of AcO super(-), F super(-) and CN super(-) ions was detec...

Description
Summary:Chlorophyll derivatives were functionalized with a trifluoroamide (TFA) group to obtain colorimetric ion sensors. Prior to this, a NO sub(2)BF sub(4)*pyridine based, chlorin nitration method was developed. The base strength dependent sensing of AcO super(-), F super(-) and CN super(-) ions was detected in aqueous media, which was enhanced in nonprotic solvents by an integration of the ditopic chelation capable amine crown-6 moiety.
