摘要：
A potassium selective fluorescent chemosensor, 2, was designed and synthesized. The molecular sensor is weakly luminescent in acetonitrile solution, but exhibits a significant increase in intensity upon addition of K+. The luminescence intensity increases reach a plateau when the K+/2 ratio is 3:2. The sensor shows a Linear fluorescent enhancement with the concentration of potassium ion in the presence of a large excess of sodium ion.
