    Porous aromatic organosilicates by non-hydrolytic sol-gel routes

  • Original language description

    A series of porous hybrid organosilicate materials was prepared by non-hydrolytic sol-gel reactions of silicon(IV) acetate with rigid aromatic building blocks bearing phenolic hydroxyl functional groups with focus on readily available compounds that werepreviously utilized for synthesis of materials such as the porous aromatic frameworks (PAFs) and covalent organic frameworks (COFs). Upon elimination of acetic acid as a byproduct, an organosilicate gel is formed in polar ether solvents. Drying in vacuooffers powdered xerogels. The synthesis procedure was optimized in order to reach the maximum degree of condensation as monitored by gravimetry. All of the prepared materials were found to be amorphous, they do however possess large specific surface areas exceeding 800 m2 g-1 and generally exhibit high thermal stability (up to 400 °C under inert gas).
