摘要：
A simple colorimetric and fluorescent chemosensor MP was designed and synthesized and its selective signaling behaviors toward Cu2+ were investigated. Under the optimized conditions, the sensor exhibited specific absorbance-on and fluorescence-on responses to Cu2+ only, which can be tuned for detection with the naked eye. These remarkable properties may allow Cu2+ to be detected directly in the presence of the other examined metal ions. The limit of detection for Cu2+ was up to 0.096 mu M. As a fluorescence turn-on sensor, cell experiments showed MP can permeate through cell membranes and react to Cu2+ within living cells.
