Synthesis and trans-cis isomerization of azobenzene dendrimers incorporating 1,2-isopropylidenefuranose rings

Azobenzene dendrimer 2 was synthesized from a known dendritic azo-tetracarboxylic acid and a dendritic amine incorporating 1,2-isopropylidenefuranose rings, and its trans-cis isomerization was studied by UV-vis absorption spectroscopy.
