一种以二苯基丁二烯为核的树状大分子在水溶液中具有显著的反式-顺式光异构量子产率。荧光寿命和波长相关激发光谱分析表明，核心丁二烯具有多种构象，其中一种或几种构象被充分扭曲以进行优先光异构化。
A diphenylbutadiene-cored dendrimer exhibited a remarkably high quantum yield fortrans-to-cisphotoisomerization in aqueous solution. Analysis of the fluorescence lifetimes and the wavelength-dependent excitation spectra suggested that the core butadiene adopts multiple conformations, one or several of which is sufficiently distorted to undergo preferential photoisomerization.
