From the monomers in the synthetic scheme below, polymers were made that were endcapped with either a UV degradable o-nitrobenzyl alcohol group or a NIR degradable bromo-coumarin group. Deprotection of these endgroups with the appropriate wavelength led to degradation of the polymer in a domino effect as depicted in the figure below.
