Complex, its preparation method, fluorinion sensor and method for detecting fluorinion

The invention provides a complex as shown in a chemical formula 1 in the specification, a preparation method of the complex, a fluorine ion sensor and a method for detecting a fluorine ion. In the chemical formula 1, m is an integer from 0 to 5, n is an integer from 0 to 4, R1, R2 and R3 are independently selected from a group composed of deuterium, tritium, halogen, a cyano group, an amino group, nitryl, hydroxyl, carboxyl, substituted or unsubstituted C2-C30 ether groups, substituted or unsubstituted C2-C30 ester groups, substituted or unsubstituted C1-C30 alkyls, substituted or unsubstituted C2-C30 alkenyls, substituted or unsubstituted C2-C30 alkynyls, substituted or unsubstituted C3-C30 cycloalkyls, substituted or unsubstituted C1-C30 alkoxyl groups, substituted or unsubstituted C3-C30 cycloalkoxyls, substituted or unsubstituted C5-C30 aryls, substituted or unsubstituted C5-C30 aryloxys and substituted or unsubstituted C3-C30 heteroaryls.

Selective and colorimetric fluoride chemosensors containing phenol hydroxyl and 1,3,4-oxadiazole groups

Two novel anion sensors, methyl 4-(5-(5-chloro-2-hydroxyphenyl)-1,3,4- oxadiazol-2-yl) benzoate (L1) and methyl 4-(5-(2-hydroxyphenyl)-1,3,4-oxadiazol- 2-yl) benzoate (L2) were reported. Their spectroscopic and colorimetric properties in CH2Cl2/CH3CN (1:2, v/v) solution for F- sensing were investigated by naked-eye, UV-vis, and fluorescence measurements. Both molecules with coplanar structure possess adjacent phenolic hydroxyl and 1,3,4-oxadiazole units, resulting in a sufficiently strong intramolecular hydrogen bond to hinder the association of most anions, but not F-, with phenolic hydroxyl hydrogen. They displayed the same color changes from colorless to yellow but different optical shifts upon addition of F-. Copyright
