A new fluorescent sensor for the detection of pyrophosphate based on a tetraphenylethylene moiety
摘要:
We have developed a new fluorescent sensor 1-2Zn based on a tetraphenylethylene (TPE) moiety for the detection of PPi. This TPE-based chemosensor showed 'turn-on' fluorescence emission according to the concentration of PPi The fluorescence enhancement upon binding of PPi to 1-2Zn resulted from the restriction of intramolecular rotation of phenyl rings in 1-2Zn.
