Fused aromatic networks as a new class of gas hydrate inhibitors

Fused aromatic networks (FANs) are attracting considerable interest in the scientific community because of their intriguing electronic properties and superior physiochemical stability due to fully fused systems. Here, a three-dimensional (3D) cage-like organic network (3D-CON) vertical two-dimensional (2D) layered ladder structure (designated as V2D-BBL structure) were studied materials for gas hydrate inhibitors outstanding high-pressure/low-temperature periodically incorporated molecular building blocks. The demonstrated remarkable performance, inhibiting formation both methane (CH4) carbon dioxide (CO2) hydrates, comparable conventional lactam-based polymers. It was determined that designed perinone moiety enables synergistic interactions with host (water) guest molecules involved nucleation. Given pre-designability inherent stability, FANs hold enormous potential industrial applications.
