通过在取代光致变色螺环吡喃存在下生长γ-环糊精晶体，得到了光致变色主客体包合物。测定了主体结构中光生光致花青客体的相对稳定性。相对于主客体晶体中的其他取代基，固体中的相互作用选择性地增强了醛取代的光花菁。
Photochromic host-guest inclusion compounds were obtained by growing crystals of gamma-cyclodextrin in the presence of substituted photochromic spiropyrans. The relative stabilities of the photogenerated photomerocyanine guests inside the host structure were determined. Interactions in the solid state selectively enhanced the aldehyde-substituted photomerocyanine relative to other substituents in the host-guest crystals.
