Surface functionalization of phosphazenenanosphere derivatives by Schiff-base-assisted metal complexes through a Si-spacer

Surface functionalization of organometallic derivatives of phosphazenenanosphere (PNS) by the metal-coordinated Schiff base through (3-chloropropyl)trimethoxysilane as a silicon linker and spacer was investigated. The PNSʹs derivative of 4,4′-sulfonyldiphenol (BPS) was added to Si–H2 saldien under ultrasonic irradiation. Metal ion (Mn2+, Ni2+or Zn2+) was loaded on the PNS–Si–H2 saldien as desired metal salt. The structure and morphology was characterized by means of FT-IR, TGA, SEM, EDX and X-ray diffraction. The average diameters of nanosphere compounds are in the range of 250–300 nm.
