Abstract
We describe the synthesis of the new open system 3 and polyether macrocycles containing an anthraquinonic system 4 and 5; their sulphur compounds 6 and 7 have also been prepared. X-Ray crystallographic study of compound 5 in the presence of calcium and barium perchlorates shows that the latter crystallizes into monoclinic and triclinic system respectively. The UV spectrometry shows that the macrocycle 5 presents complexing properties toward Ca2+, Ba2+ and Pb2+ ions. By contrast macrocycle 4 selectively complexes Pb2+ ions; these complexes were observed by electrospray, IR and UV spectrophotometry.
