摘要
Coumarin derivatives with non-polar substituents at the 6 or 7 position undergoes photodimerization in the presence of CB[ 8] in water to give the syn dimer as the major product. It is postulated that these neutral coumarins form dynamic complexes in the presence of CB[ 8] and the product selectivity is reflective of the type of complex, available volume in the CB[ 8] cavity and relative rate of photodimerization inside and outside the CB[ 8] cavity.
