Condensation of the functionalised cyclophosphazene aldehyde, N3P3(OC6H5)5(m-OC6H4-CHO) (3) with pyrrole affords the tetraphenylporphyrin (4) containing the cyclophosphazene unit. This has been characterised by spectroscopic and analytical methods. Kinetics of metallation (Cu2+, Zn2+) of (4) indicate slower rates of insertion relative to normal tetraphenylporphyrins. The esr spectrum indicates an axial symmetry for the Cu2+ derivative (6).
