In order to elucidate photophysical and steric factors influencing extent and reaction pathway of a reaction process involving inclusion compounds the photoisomerization of cis- or trans-stilbene and cis- or trans- methylcinnamate has been studied in cavities of deoxycholic acid or Ni(II)-(4-picoline)4-(NCS)2.The observed isomerization yields have been correlated with the excitation energy transfer processes which occur between host and guest molecules as well as with the symmetry properties of the various species involved during the isomerization process.
