the mixedcrystal phase. The kinetic data concerning the analysis of the topochemical photoproducts revealed that the following growth of the mixedcrystal phase was triggered by each of the mixedcrystal nuclei and that the growth of the mixedcrystal phase was accelerated by either thermal annealing or exposure in humidity. During the early stage of mixedcrystal growth, the growth rate was nearly
α-氰基-4-[2-(4-吡啶基)乙烯基]肉桂酸乙酯和α-氰基-4-[2-(4-吡啶基)乙烯基]肉桂酸乙酯的混合晶体通过简单的研磨以固态形成。通过研磨时 X 射线衍射图的变化以及光产物的 1 H NMR 和 HPLC 分析来确定混合晶体的形成。根据多次尝试,得出的结论是机械处理对于混合晶相的形成是必要的。关于拓扑化学光产物分析的动力学数据表明,混合晶相的后续生长是由每个混合晶核触发的,并且混合晶相的生长通过热退火或暴露在潮湿环境中加速。在混晶生长初期,
