In contrast to the traditional methods that rely on prefabricated supports or postsynthetic triazine integration, our strategy allows triazine moieties to be covalently embedded in situ inside the silica backbone, providing uniform distribution and improved structural integrity. The produced silica-based porous organic polymers (POPs) have high thermal stability (up to 250 °C) along with high specific surface areas (200–600 m²g^–1). The presence of hierarchical porosity (meso- and microporosity) guarantees quick diffusion of the reactant and intermediates during catalytic reactions in addition to facilitating efficient CO₂ adsorption at the pore surfaces. Using this structural advantage, a two-step CO₂-valorization method was investigated: first, CO₂ was converted to cyclic carbonates, and then it was reduced to methanol. Due to high porosity and easily accessible active sites, these hybrid materials catalyze the transformation of the carbonate to methanol, facilitating effective hydride transfer and intermediate conversion. Among the three silica-incorporated POPs, SL-1-Silica-POP produced the highest methanol yield of 20.5 mmol g^–1 in the hydrogenation of epichlorohydrin carbonate by using phenylsilane as the hydride source. 2026-09-28T00:00:00Z Text Journal contribution 10.1021/acs.chemmater.6c01749.s001 https://figshare.com/articles/journal_contribution/One-Pot_Synthesis_of_Triazine-Embedded_Hierarchically_Porous_Organosilica_Polymers_via_Tandem_Condensation_for_Carbon_Capture_and_Conversion/34020589 CC BY-NC 4.0
