摘要:Abstract(#br)We studied some ionic liquids (ILs) belonging to the pyridinium class under photocatalytic treatment. In particularly, we analysed how the length of the alkyl chain, the kind of inorganic ion and the type of substituents could influence the disappearance rate, the mi...

摘要:Abstract(#br)A simple pyridinium-based chiral receptor 1 containing l -valine as the chiral source has been designed and synthesized. The receptor 1 fluorometrically recognizes d -lactate over l -lactate in CH 3 CN with an enantiomeric fluorescence ratio ( ef ) of 5.32.
