High Pressure Synthesis of All-Transoid Polycarbonyl [—(C═O)—]n in a Zeolite

A study was conducted to demonstrate the synthesis of high pressure synthesis of all-transoid polycarbonyl [-(C=O)]n in a zeolite. The study also demonstrated the feasibility of inducing the self-assembly of dense CO in the spatially subnano-confined region of the channels of an electrically neutral, non-catalytic, hydrophobic, and all SiO2 zeolite silicalite. It was observed that the insertion of simple guest molecules, such as Ar and CO2 in the channels of this zeolite deactivated the pressure induced amorphization of the framework up to at least 25 GPa.
