Incorporation of cyclophosphazene units into the organosilica frameworks.

Cyclophosphazene induces a synergy effect in achieving high surface areas.

The specific surface areas of the CPMOs varies from 34 to 1034 m² g⁻¹.

The CPMOs show very fast removal of Cr (VI) in the aqueous solution (99.24 mg g⁻¹).

Maximum CO₂ uptake of 2.19 mmol g⁻¹ was observed at 273 K.
