Preparation of a library of EDTA amide x-aminenaphthalene-y-sulfonic acid derivatives on solid phase and their fluorescence behavior toward transition metals.

In this work, we report the synthesis of a combinatorial library of 80 derivatives of EDTA amide x-aminenaphthalene-y-sulfonic acid on four different supports with variable length linker. The sensing fluorescence behavior of these materials for transitions metals was studied by packing the beads into a conventional flow-through cell in a continuous flow injection set up. The fluorescence emission response of these materials shows that sensors supported in Argopore (a) with the fluorescence moiety of 1-aminenaphthalene-4-sulfonic acid behaves like dosimeter for copper.
