Abstract
© 2016 Elsevier B.V. All rights reserved.New polydentate ligands based on hyperbranched second and third generation polyesters containing terminal (3-diethylamino)propionate fragments and their polynuclear copper(II) complexes were synthesized and characterized by spectroscopic methods. The acid-base properties spectroscopy determined that the functionalization degree of the diethylamine-modified hyperbranched polyesters (LI, LII) increases from the second (56%) to third (81%) generation. The polynuclear complexes Cu(II)-LI and Cu(II)-LII were observed. A coordination site of the complexes contains paramagnetic fragment CuN2O2Solv2 where Solv is H2O or DMSO. The hyperbranched poly(ester amine) of the third generation have strong antifungal activity against Aspergillus fumigatus culture, and its metal complex is active against Candida albicans culture
