Connecting cyclophosphazenes via ring N-centres with covalent linkers

Two cyclotriphosphazene rings can be covalently linked via ring N-centres by a 2-butene-1,4-diyl unit and vice versa a cyclotriphosphazene molecule is able to bridge two cinnamyl groups via two ring N-centres yielding in either case dicationic assemblies which offers a route to novel polycations.
