摘要：
We have developed novel fluorescence probes for sodium cation based on photoinduced electron transfer (PeT). In this study, we rationally designed new probes and succeeded in achieving fluorescence enhancement upon sodium ion binding by reducing the HOMO energy level of the chelator group within the probe molecule. Our new probes show low pH dependency, possibly because of their simple structures. Our results confirm the value of rational probe design based on PeT. (C) 2004 Elsevier Ltd. All rights reserved.
