Ten new tetraheterocyclic macrocyclic ligands 2-4 in the porphyrinogen series were prepared. Their structures differ from 1 in (1) the type of junction between hetrocycles (NCH2C or CCH2C),(2) the donor nature of the complexation sites,(3) the five-or six- membered geometry of the included heterocycles, and (4) their symmetry. The capabilities of 2-4 for extraction and transport of alkali metal and NH4+ cations were less than those of 1. ...
