Abstract: A series of novel dendrons and dendrimers skeleton-constructed with azobenzene moiety were synthesized with 4-carboxy-4'-(1,2-propanediolether)-azobenzene as an AB2 monomer and 4-carboxy-4'-(n-butylether)-azobenzene as a peripheral monomer via a convergent approach and proceeding in a repeated stepwise growth manner. The NMR, GPC, and MALDI-TOF-MS measurements show that the obtained products possess regular molecular architecture and thus monodispersed molecular weights. It will be of interest to investigate the self assemble behavior of the polymers and the promising applications for the dendrimers as the dendritic boxes in the subsequent works.
