摘要：

Let's twist again: While the photoisomerization of stilbene analogues in fluid solution occurs by a one-bond-flip mechanism and involves only configurational changes, in a solid solution (glass) a Hula-twist mechanism operates and results in conformational as well as configurational changes (see scheme).
