Abstract

Two dendrimer cores, 5 and 12, containing o-nitrobenzyl photolabile moieties have been synthesized from piperonal in five and eight steps, respectively. Methylated core analogs 6 and 13 undergo clean photocleavage as indicated by the evolution of isosbestic points in the UV spectra during photolysis and the observation of degradation products by 1H NMR. These dendrimer cores serve as precursors to dendrimer-based photodegradable materials.
