In view of environmental pollution control and purification of natural gases, developing ideal porous materials for small gas molecule (hydrogen, methane and carbon dioxide) capture is an important, pressing challenge. Accordingly, herein, three microporous organic polymers (MOP-Ad) have been synthesized by Suzuki coupling polymerization of 1,3,5,7-tetrakis(4-bromophenyl)adamantane “knots” with three phenylboronic acid-type “rods”. Gas adsorption studies of the MOP-Ad materials demonstrated their permanent porosity and good gas storage capabilities (1.07 wt% H₂ at 77.3 K and 1.13 bar, 10.3 wt% CO₂ and 2.4 wt% CH₄ at 273.1 K and 1.13 bar), as well as moderate CO₂/CH₄ adsorption selectivity. Moreover, high thermal stability (up to 520 °C) and remarkable chemical resistance to strong acids and bases were found in these polymers, making them suitable candidates as gas storage materials in harsh chemical environments.

合成热化学稳定的基于四苯基金刚烷的微孔聚合物作为储气材料†

考虑到环境污染的控制和天然气的净化，开发用于捕集小气体分子（氢气，甲烷和二氧化碳）的理想多孔材料是一项重要而紧迫的挑战。因此，本文中，已经通过1,3,5,7-四（4-溴苯基）金刚烷“结”与三个苯基硼酸型“棒”的Suzuki偶联聚合合成了三种微孔有机聚合物（MOP-Ad）。对MOP-Ad材料的气体吸附研究表明，它们具有永久的孔隙率和良好的储气能力（在77.3 K和1.13 bar下为1.07 wt％H ₂，在273.1 K和1.13 bar下为10.3 wt％CO ₂和2.4 wt％CH ₄），以及适度的CO ₂ / CH ₄吸附选择性。此外，在这些聚合物中还发现了高热稳定性（最高520°C）以及对强酸和强碱的出色化学耐受性，使其成为在恶劣化学环境中用作储气材料的候选材料。
