两亲性烯二炔核心的树枝状聚合物制备为纯顺式和反式异构体。所有树枝状大分子均具有荧光性，荧光量子产率为0.10 ~ 0.64，在THF中进行了有效的光化学异构化，量子产率为0.22 ~ 0.50。在水中，发生了其他光化学反应。荧光或三重态寿命也受到树枝状聚合物生成和溶剂极性的强烈影响。讨论了新型光敏树枝状大分子的结构与光化学性能的关系。
Amphiphilic enediyne-cored dendrimers were prepared as pure cis and trans isomers. All dendrimers were fluorescent to give fluorescence quantum yield of 0.10―0.64, and they underwent efficient photochemical isomerization with quantum yields of 0.22―0.50 in THF. In water, other photochemical reactions took place. Fluorescence or triplet lifetimes were also strongly affected by dendrimer generation and solvent polarity. The structure―photochemical property relationship of new photoresponsive dendrimers is discussed.
