<jats:title>Abstract</jats:title> <jats:p>Azobenzene dendrimer E-2, having water-soluble dendrons at the ortho-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 Z-to-E thermal isomerization of 2 also greatly depended on the water/EtOH ratio.</jats:p>
