As a continuation of our work on the fluorescent probes for metal ions,biothiol and HOCl [1-6],we developed a ratiometric probe for sensing pH based on coumarin-rhodamine dyad.
As a continuation of our work on fluorescent probes for biothiols,we presented here a new fluorescent probe constructed by 3-hydroxyflavone and 2-(pyridin-2-yl-disulfanyl)benzoic acid(PBA) moiety.
