Synthesis and isomerization of azobenzene dendrimers.
3,3',5,5'-Tetramethoxyazobenzene and related meta-substituted azobenzene dendrimers show the first evidence of the dendritic effect on trans-to-cis photoisomerization; the thermodynamic parameters for cis-to-trans isomerization have been determined.
