Abstract

Polyphosphoesters (PPEs) are versatile polymers with applications in tissue engineering, drug delivery, and materials science. This study systematically investigates the copolymerization of different PPE subclasses (side-chain and in-chain phosphonates, phosphates, and thiophosphates) using organocatalysis. Reactivity ratios were determined for binary and ternary copolymers, revealing gradient copolymers with tunable amphiphilicity and microstructure. These copolymers self-assembled into nanostructures in aqueous solutions, and 31P MRI imaging confirmed their potential as MRI-traceable nanomaterials, expanding their possibilities for drug delivery and theranostics.
