Abstract:
The reversible formation of a dative bond between the boron center (M) of the host and the N atom of the primary amine, with simultaneous formation of hydrogen bonds between the amine H atoms and two oxygen atoms (D) of the crown ether host presents a new concept in molecular recognition (depicted schematically right). The control of the degree and direction of the molecular recognition by variation of the groups R on the amine is unprecedented
