Abstract

Poly(4-(((2,3-dihydrothieno[3,4-b][1,4]dioxin-2-yl)methoxy)methyl)benzoic acid) (PEDOT-Ph-COOH) was facilely synthesized by the direct electropolymerization of 4-(((2,3-dihydrothieno[3,4-b][1,4]dioxin-2-yl)methoxy)methyl)benzoic acid (EDOT-Ph-COOH) in CH2Cl2-Bu4NPF6 (0.10 M) system, and the PEDOT-Ph-COOH films were systematically investigated. The results displayed that the film had excellent reversible redox activities, good electrochemical performance, and rough and compact surface. Finally, the PEDOT-Ph-COOH film was used as an optical chemo-sensor for the highly selective and sensitive detection of F− PO43-, HCO3-, S2O32-, Cu2+, and Fe3+ in dimethyl sulfoxide. Satisfactory results indicated that optical chemo-sensor based on PEDOT-Ph-COOH possessed an excellent sensing performance and enhanced optical response, and it might be as potential promising materials, such as electrochromic devices, supercapacitors and so on.
