Easy-to-make tripodal tris-thiourea receptors based upon tris(2-aminoethyl)amine are capable of chloride/bicarbonate transport and as such represent a new class of bicarbonate transport agent.

The synthesis and crystal structure of a new 34-membered N6O4-donor macrocycle2 is reported. Solvent extraction experiments (water/chloroform) indicated that 2 acts as an efficient extractant towards silver(I) and zinc(II) at pH values beyond 6 while the extraction of iodide and chromate occurs below this pH. A competitive metal extraction experiment at pH 7.2 in which the perchlorate salts of cobalt(II)

An acyclic receptor 1 with a binding cavity surrounded by electron-rich aryl surfaces has been synthesized for binding quaternary ammonium salts through cation-pi interactions. The association constants of the receptor 1 with salts in CDCl3 depend on the anions due to the hydrogen bonds between the exchangeable protons in the receptor 1 and anions.

A series of fluorinated tripodal tris-thioureas function as highly active anion transporters across lipid bilayers and cell membranes. Here, we investigate their mechanism of action using anion transport assays in cells and synthetic vesicles and molecular modelling of transporter–lipid interactions. When compared with non-fluorinated analogues, fluorinated compounds demonstrate a different mechanism
