摘要
From a combination of X-ray crystallography, solid-state NMR, and theoretical calculations, a model of a beta-cyclodextrin (beta-CD)-coumarin inclusion complex has been developed which characterizes the complex as a 2:3 beta-CD-coumarin system with the coumarin molecules located in PCD dimer 'reaction nano-tubes'; the model explains the reported yield for the coumarin photodimerization reaction carried out in powdered solids.
