Hyperbranched polyester poly(3-diethylaminepropionate)s and their copper(II) complexes: Synthesis, characterization and biological investigation

© 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

CERTIFICATION OF TEACHERS COLLEGE:ORGANIZATIONAL ASPECTS

This paper discusses the organizational issues of certification of teachers college. The author proposes a conceptual approach as a change in the structure and content of certification - a systematic approach. Marked subjects and structure of certification showing their function in the process
