Abstract

Graphical abstract: Highlights: Effective exaction of MCl4 n− (Au, Pt, or Pd) from Nan MCl4 water solution has been achieved. It relies on a tetraimidazolium macrocyclic anion receptor. The extraction scale could be expanded to hundred milligram and yield was up to 97%. Abstract: Highly effective exaction (up to 97%) of noble metal Au, Pt, or Pd as MCl4 n− form (i.e., AuCl4 −, PtCl4 2−, or PdCl4 2− ) from Nan MCl4 aqueous solution have been achieved on the basis of the interactions between MCl4 n− and cyclo[2](2, 6-di(1H-imidazol-1-yl)pyridine)[2](2, 6-bisbromomethyl)pyridine (1 4+ ).
