A polyhedral oligomeric silsesquioxane functionalized copper trimesate†
Abstract
A metal–organic framework (MOF), copper trimesate (Cu3(BTC)2), was selectively functionalized with aminopropylisooctyl polyhedral oligomeric silsesquioxane (O-POSS) to make the external surface of Cu3(BTC)2 hydrophobic and thereby enhance the stability of the material against humidity. POSS modification was also successfully applied to other MOFs such as MOF-74 and MIL-100.
