Abstract
The paper deals with the synthesis and physico-chemical characterization of polydimethylsiloxanes modified with piperazinyl ligand groups and of their Cu(II) complexes. 1H NMR, Fourier transform infrared, UV-VIS and electron spin resonance spectroscopy were used to follow the structure of the coordination compounds. Three different types of copper bonding to the macromolecular ligand were identified. An uniform distribution of Cu(II) cations into the polymeric material was evidenced by an environmental scanning electron microscopy/microanalysis by energy dispersive spectrometry combined method.
