Description
Summary:Miniature gas jars with lids: Salt‐free decamethylcucurbit[5]uril (MeCuc5) powder, absorbs N2, O2, Ar, N2O, NO, CO, and CO2 selectively at room temperature and desorbs at 110°C, this process can be carried out repeatedly. In contrast, all noble gases from He to Xe were encapsulated inside MeCuc5 in solution and the crystal structures of the gas inclusion complexes were determined (see picture for Xe complex).
