查询词典 sulfur black

In the titration experiment of NMR and IR spectroscopy, we can understand how sensors binding with metal ions: the two carbonyl group and crown ether group cooperated in binding with metal ions. Furthermore, by altering the "oxygen" atoms of crown ether to "sulfur", we can change the binding affinity to the soft metal: cupper. It shows 60-fold enhancement of fluorescence.
