Abstract

Cyclodextrin based carbonate nanosponges were synthetized starting from native β-cylodextrin and active carbonyl compounds i.e. carbonildiimidazole. In this work they were used to form inclusion complexes with three different gases i.e. 1-methylcyclopropene, oxygen and carbon dioxide. The encapsulation of gases were proved by direct reaction to known adduct (1-methylcyclopropene), by gravimetric analysis (CO2) and by oxymeter (Oxygen). The complexetion of oxygen or carbon dioxide could be useful for many biomedical applications. In particular the oxygen-filled nanosponges could supply oxygen to the hypoxic tissues which are present in various deseases. 1-methylcyclopropene included in β-cyclodextrin nanosponges showed superior antiethylenic performances in long lasting cut flowers in comparison with marketed products.
