Self-Assembly of a Molecular Floral Lace with One-Dimensional Channels and Inclusion of Glucose

Abstract

A three-dimensional network with one-dimensional channels (see picture) has been self-assembled from the nickel(II) complex of cyclam and 1,3,5-benzenetricarboxylate in water through hydrogen-bond formation. The channels have an appropriate diameter (10.3 Å) to include D-glucose with a formation constant of K_f =(1.38±0.01)×10⁴ M^-1 . Under similar conditions maltose is not included.
