Azobenzene star polymers

Other complex architectures, such as azobenzene star polymers (Angiolini et al, 2006) and molecular brushes (Lee et al, 2006a), have also been prepared, although their optical data storage capabilities have not yet been explored. Advances in these new macromolecular architectures are generally based on the combination of CRP and click chemistry reactions as a synthetic tool for achieving more complex smart polymers. 

Tris(styiylbipyildine)zinc(II) complexes functionalized by dialkylamino-azobenzene groups have recently been designed by Le Bozec et al. to prepare photoisomerizable star-shaped nonlinear optical polymers 7 [25].
