Dynamic Libraries From Hydrogen Bonding Interactions Supramolecular DLs

5 Dynamic Libraries From Hydrogen Bonding Interactions (Supramolecular DLs) 

Among the cyclic species the dimer was demonstrated to form always in the largest extent (cyclic monomer is too strained to form in aU cases). 

Thus EM2 of4,150,14, 48, 6 and 110 mM were estimated for the cyclic dimers present in the DLs generated from Mj Upy a, Mj Upy b, Mj Upy c, Mj Upy d, Mj Upy e and Mj Upy f, respectively. It is worth noting that substitution of the alkyl linkers with methyl groups next to the Upy moieties can strongly increase the EM2 value (compare 4 with 150 mM), probably
