トリアジン部位をシリカ骨格内にin situで共有結合導入した3種の階層多孔性有機シリカポリマーを、タンデム縮合により一段階で合成した初の報告。高い熱安定性と200–600 m²g⁻¹の比表面積、メソ・ミクロ細孔を併せ持つ。CO2を環状カーボネート経由でメタノールへ変換する二段階プロセスに適用し、SL-1-Silica-POPが20.5 mmol g⁻¹の最高メタノール収率を示した。
English
First one-pot tandem-condensation route to three covalently bonded hierarchically porous organosilica polymers with in-situ embedded triazine moieties. The materials show high thermal stability (up to 250 °C), surface areas of 200–600 m²g⁻¹, and hierarchical micro/mesoporosity enabling fast diffusion and efficient CO2 adsorption. Applied to a two-step CO2 valorization (cyclic carbonate then methanol), SL-1-Silica-POP gave the highest methanol yield of 20.5 mmol g⁻¹.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX文脈では、CO2回収・利用（CCU）の要素技術として、グリーン成長戦略やGX推進法が掲げるカーボンリサイクル実装の基礎研究的位置づけにある。ただし現段階では実験室レベルの材料開発であり、SSBJ開示や投資家対応に直接資するものではない。
In the global GX context
Adds to the global CCUS/CCU materials literature by demonstrating a scalable one-pot route to triazine-functionalized organosilica sorbents/catalysts, relevant to carbon-capture-and-utilization pathways that underpin net-zero transition scenarios. It is upstream materials science rather than disclosure or policy scholarship.

📄 Abstract（原文）
Abstract A simple one-step route for designing three covalently bonded porous organosilica polymers via tandem condensation, bearing an adjustable triazine moiety and N–Si cooperative microenvironments, has been reported for the first time. 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.
