A macrocyclic bis-urea receptor (L1) and two acyclic bis-urea analogues (L2 and L3) have been synthesized. The crystal structure of L1 was obtained. The experimental results show that the receptor L1 has high selectivity to H2PO4 ?. Meanwhile, compared with the acyclic receptors L2 and L3, L1 has higher binding ability to H2PO4 ?. The results of density functional theory (DFT) calculations deepened our understanding on L1 conformations stability and its anion-binding property.

Four heteroditopic macrocyclic ligands incorporating both anion coordination sites (tris-urea units) and a cation binding fragment (polyether) were designed for possible application in molecular devices. Sandwich-type phosphate complexes were formed, which display a reversible rotation around the anion upon protonation/deprotonation of phosphate and binding of the cation (Emim+).

supporting information; experimental part, p. 6021 - 6023 (2011/08/02)
A new dicopper(i) complex is reported that can be incorporated into extended architectures through multitopic carboxylate linkers; reversible carboxylate templation under pH control led to the formation of [2+2] and [3+3] metallomacrocycles.
