Enantiodifferentiating photoisomerization of (Z)-cyclooctene included and sensitized by m-methoxybenzoyl-beta-cyclodextrin gave chiral (E)-isomers in up to 46% enantiomeric excess, which is the highest value ever reported for supramolecular photochirogenesis with analogous hosts, thus demonstrating the crucial role of the sensitizer-spacer moiety in supramolecular photochirogenic systems.
间甲氧基苯甲酰基-β-环糊精包合并敏化的(Z)-环辛烯的对映体选择性光异构化反应生成了对映体过量高达46%的手性(E)-异构体，这是使用类似主体的超分子光致手性生成所报道的最高值，从而证明了敏化剂-间隔基部分在超分子光致手性体系中的关键作用。
