Abstract

Abstract : A red fluorescent and colorimetric probe (NDI-Py ) exhibited high selectivity and sensitivity towards copper ions both in solution and on silica gel plates. Abstract : Herein, a red fluorescent and colorimetric probe (NDI-Py ) based on naphthalene diimide was designed and synthesized, which exhibited rapid response, high sensitivity and selectivity towards copper ions, and the detection limit was as low as 0.97 μM in solution. Furthermore, NDI-Py demonstrated a strong red emission in the aggregated state because of its non-planar structure. Thus, it can act as a test strip to conveniently monitor copper ions with the detection limit as low as 2.0 μM.
