Colorimetric “naked eye” detection of CN⁻, F⁻, CH₃COO⁻and H₂PO₄⁻ions by highly nonplanar electron deficient perhaloporphyrins

Abstract

Highly nonplanar electron deficient perhaloporphyrins were utilized for the detection of basic anions such as CN⁻, F⁻, CH₃COO⁻and H₂PO₄⁻<italic>via</italic>anion induced deprotonation. These sensors can be reusable without loss of their sensing ability.
