Molecular composites based on first-sphere coordination of calcium ions by a cyclodextrin

Autor: Pierrette Charpin, Ioannis Nicolis, Colette de Rango, Mohamed Selkti, Anthony W. Coleman, Françoise Villain

Two organic-inorganic composites based on first-sphere coordination of calcium ions by α-cyclodextrin, highlight the possible creation of different architectures, even when involving identical molecular building blocks and inorganic clusters. In bot
