Abstract

A highly selective, sensitive and convenient probe, based on a photochromic and acidochromic benzoxazole-spiropyran derivative, was developed for visual Cu2+ detection. The detection remained unaffected by competing ions and achieved a detection limit of 10−7 M in both solution and test strip formats.
