Six cyclic stilbene derivatives with hindered free rotation around the C(vinyl)–C(phenyl) single bond were synthesized by McMurry coupling. The torsion angles around the double and the single bond, and the CC bond length were obtained for many of the compounds from their solid-state structures. The photochemical isomerization was subsequently investigated for all derivatives under various conditions

stationary S1 point on the cis side and two perpendicular-pyramidalized stationary points, to be reached from the former over 300 and 680 cm–1 barrier. Implications for parent stilbene are discussed; in this case we also see evidence for the trans-to-cis adiabatic path, as in stiff-stilbene. Very similar viscositydependence for the two compounds supports the common isomerization pathway: torsion about
