New in ACS Materials Au ⚗️ TU-42 COFs create distinct Fe–N/O and Ni–N/O/Cl sites. Hydroxyl–ligand H-bonding tunes the Fe ligand field, promotes nitrate activation and favors ammonia formation, while saturated Ni sites restrict substrate access. ✨

【論文公開】ACS Materials Au ⚗️
ビピリジンと水酸基を備えたCOF「TU-42」にFeまたはNiを導入。開放的なFe–N/O環境では、水酸基と配位酢酸の水素結合が配位子場と酸化還元特性を動的に調整し、硝酸の活性化とアンモニア生成を促進します。一方、配位飽和したNi–N/O/Cl環境では基質接近と反応経路が制限されます✨

Most citizens of the galaxy are ordinary people, just trying to make it through the day. Some have families. Some have jobs. Some are four. Life goes on.
