文摘

Three new rhodamine Schiff base sensors 1a-1c have been designed and synthesized as highly sensitive and selective ¡°off-on¡± chemosensors for Cu²⁺ detection via the rhodamine ring-opening approach. The sensors display remarkably Cu²⁺-selective orange fluorescence and pink color switch over a wide range of tested metal ions. Fluorescent imaging of Cu²⁺ in living cells is also successfully demonstrated.
