IntroductionLight-responsive dynamic polymer networks consist of dynamic interactions that allow for rearrangements of their network topology and

adaptation of their properties in response to light.

3IntroductionLight as stimulus: lprecise temporal and spatial control;lcritically allows highly specific reaction channels to be selectively addressed through wave-length and intensity;lremote control.

lnot as universal as thermal induced exchange;

lusually high irradiation intensity;

lusually requires highly functionalized monomers or oligomers
