A novel flexible multisite cyclotetraphosphazene ligand, octakis(4-pyridylamino)cyclotetraphosphazene (OPCP), was synthesized through a new method, and it represents the first fully substituted pyridylaminocylcophosphazene ligand with eight coordinating arms. Self-assemblies of OPCP and different transition metal ions result in three novel 3D coordination polymers, in which the Cd(II) complex exhibits a quite strong blue emission.
