A novel rapid ion colorimetric sensing material for iron(III) ions was developed from poly(γ-glutamic acid) and 3,4-dihydro-3-(2′-ethyl hydroxyl)-6-ethyl-1,3,2H-benzoxazine (ethyl-Bx). The benzoxazine as an ionophore segment was grafted into γ-PGA backbone via the esterification reaction, which is a...
