In this period, we have developed control the enantioselectivity of alkylation and michael addition by using chiral molecules. Also, we have researched the molecular recognition and sensing that is focused on the development of novel artificial receptors or molecular sensors for the selective recognition sensing of biogenic species such as metal ions, cyanide, ammonium and amines.
