Abstract Selected 4-oxybenzaldehyde and 2,2-dioxybiphenyl cyclotriphosphazene derivatives were synthesized via substitution reactions through tailored control. The reactions of cyclotriphosphazene with 4-oxybenzaldehyde and 2,2-dioxybiphenyl gave the following synthesized derivatives: one mono-substituted open-chain compound, N3P3Cl5(O2C7H5) (1, 69%); mono spiro, N3P3Cl4(O2C12H8) (2, 91.1%); non-gem tri-substituted, N3P3Cl3 (O6C21H15) (3, 17%); dispiro, N3P3Cl2(O4C24H16) (4, 92.3%); penta-substituted, N3P3Cl(O10C35H25) (5, 92%)；hexa-substituted, N3P3(O12C42H30). Most of these derivatives (1–6) are obtained with good yield (up to 97%), This work provides a simple and available approach to obtain versatile cyclotriphosphazene derivatives, which is expected to further promote the use of HCCP as phosphorus platform for the construction of multi-functional materials.
