摘要

A series of aminoalkyl phosphoamide compounds of the general formula O=P(NH) ₃(CH ₂) _n(NH ₂) ₃ (n=2, 3, 4, 6) and [O=P(NH) ₂(CH ₂) ₂(NH ₂) ₂] ₂ have been prepared by reacting phosphoryl trichloride with diamines, and their pH-modulated gelation and self-assembly behaviour are reported. pH-reversible hydrogels are formed in neutral water by the physical entanglement oriented by hydrogen bonds. Highly polar nature of these compounds affords multiple sites for supramolecular interactions, leading to the self-assembled nanostructures with different morphologies according to pH conditions.
