• The photodimerization of acenaphthylene in liquid crystalline media exhibiting cholesteric or nematic phase was studied from the view point of the stereoselectivity of the products. In the cholesteric phase <I>trans</I>-isomer formation increased remarkably and the ratio of the <I>trans</I>-isomer to <I>cis</I>-isomer depended significantly upon the acenaphthylene concentration. These results suggest a steric effect of the cholesteric phase structure on stereoselectivity on photodimerization compared with the predominant <I>cis</I>-isomer formation in the nematic phase.
