pH-Dependent supramolecular self-assemblies of copper(ii) (fluorene-9,9-diyl)dipropanoic acid complexes†
Abstract
Four cupric complexes (1–4) with a newly designed ligand – (fluorene-9,9-diyl)dipropanoic acid – were obtained under different pH conditions. These complexes exhibit pH-dependent supramolecular self-assembly morphologies as 0D, 1D and 2D architectures, among which 1D water channels are formed by a triple winding helical chain with opposite chiral configurations in 3.
