In silico design of adamantane derived organic superbases with an extended hydrogen bond network and their use as molecular containers for the storage of H2 and CO2

Autor: Bishwajit Ganguly, Krishnendu Khamaru

Publikováno v: RSC Advances. 5:102247-102255

Density functional (DFT) calculations predicted that amine substituted adamantane derivatives can function as organic superbases in the gas phase and in acetonitrile solution. The designed superbases have shown much higher basicity compared to the pr
