Luminescent Poly(siloxane-urethane) Composites Based on Various Phenyleuropiumsiloxanes: Synthesis and Properties

Poly(siloxane-urethane)s are an unique class of organosilicon copolymers that combine valuable properties of both silicones and polyurethanes. In this study a series of polymer films based on poly(siloxane-urethane) was prepared and fully characterized. A modern synthetic route developed by our group earlier based on utilization of organoeuropiumsiloxanes as luminescent agents for the preparation of luminescent polymers was used. The effect of the nature of phenyleuropiumsiloxanes of different structures on mechanical, thermal as well as optical properties of composites was studied. It was shown that oligomeric phenyleuropiumsiloxane in combination with beta-diketone ligand provides the most prospect composite materials with intense luminescence.
