We thank Dr. Alabugin for the calculated energies of the conformers of 2. X.-S. Wang, H.-R. Li, L. U. Colmenares, and D. Chang participated in the early part of the work described here.
Graphical Abstract
Let's twist again: Während es sich bei der Photoisomerisierung von Stilbenderivaten in Lösung lediglich um eine Änderung der Konfiguration handelt, erfolgt im Festkörper eine Hula-Twist-Isomerisierung, die auch konformative Änderungen einschließt (siehe Schema).

As expected, the Z isomer has a shorter retention time than the E isomer on silica gel.
