Volume-demanding cis-trans photoisomerization of the aromatic substituted alkenes 1-3 in the solid state at room temperature and at 50 °C is presented. Alkene 3 did not undergo the cis-trans isomerization in the solid state either at room temperature or at 50 °C. The importance of the presence of void space near the reaction center to facilitate the large volume change during cis-trans photoisomerization is discussed.
