Polyphosphoramidates That Undergo Acid-Triggered Backbone Degradation Academic Article uri icon

abstract

  • 2017 American Chemical Society. The direct and facile synthesis of polyphosphoramidates (PPAs) with acid-labile phosphoramidate backbone linkages are reported, together with demonstration of their hydrolytic degradability, evaluated under acidic conditions. The introduction of acid-labile linkages along the polymer backbone led to rapid degradation of the polymer backbone dependent upon the environmental stimuli. An oxazaphospholidine monomer bearing a phosphoramidate linkage was designed and synthesized to afford the PPAs via organobase-catalyzed ring-opening polymerization in a controlled manner. The hydrolytic degradation of the PPAs was studied, revealing breakdown of the polymer backbone through cleavage of the phosphoramidate linkages under acidic conditions.
