Aminosilyl derivatives of hyperbranched polyethers and their metal complexes

Abstract

Surface modification of nano-sized hyperbranched polymers with the fragments capable of effective complexation makes it possible to synthesize coordination compounds with practically useful properties. It was demonstrated previously that the modification is possible of non-toxic hyperbranched polyether polyols with acid fragments followed by the synthesis of the appropriate metal complexes possessing biochemical activity [1, 2]. Modification of hyperbranched polyether polyols with aminosilyl groups will provide multifunctional compounds that combine the ability to effective complex formation with the hydrogen bonding with biosubstrates. A similar approach was found very useful in creating next-generation drugs [3] and developing advanced optoelectronic systems [4]. The hyperbranched polyether polyols of the second generation were used by us as precursors of non-toxic, water-soluble polyether polyalkoxysilylamines. Modification of the terminal hydroxy groups of aminosilane was performed as follows: DOI: 10.1134/S1070363211050227
