Abstract:
Novel colorimetric sensors based on meso-2,3-dimercaptosuccinic acid nanoframes templated by a metal-organic framework were developed to detect heavy metal ions. Highly specific color changes in response to various heavy metal ions were employed for the easy detection and differentiation of heavy metal ions.
