摘要：
Sensor 1 was developed as the first example of a fluorescence-enhanced Al3+ sensor with unique dual-channel emissions. The addition of Al3+ to 1 elicits a large fluorescence enhancement by inhibition of a quenching Photoinduced electron-transfer (PET) channel and also a dramatic fluorescence enhancement due to promotion of an emissive excimer channel formation, The dual-channel fluorescence-enhanced response of the sensor contributes to its high sensitivity and selectivity.
