In this study, we prepared two kinds of monomers, one clickable phospholane monomer and one hydrophobic monomer respectively, by coupling 2-chloro-2-oxo-1,3,2-dioxaphospholane with 3-butyn-1-ol and 2-ethyl-1-butanol  The novel diblock polyphosphoester was synthesized from those two monomers by organocatalyzed ring-opening polymerization in a one-pot manner.  Following thiol-yne reactions were applied on this polymer precursor for four amphiphilic diblock polyphosphoesters with different charge types, such as anionic, cationic, zwitterionic and non-ionic.  The self-assembly behaviors of those four polymers were also studied.  This presentation will discuss the synthesis, characterization and future applications of this amphiphilic diblock polyphosphoester system.
