Abstract

Azobenzene dendrimer <B>E-2</B>, having water-soluble dendrons at the <I>ortho</I>-position in azobenzene, showed novel solvatochromism with changing the solvent ratio of water/EtOH which is based on the intramolecular hydrophobic interaction due to poly-aryl(ether) dendrons. The thermodynamic parameters for <I>Z</I>-to-<I>E</I> thermal isomerization of <B>2</B> also greatly depended on the water/EtOH ratio.
