Designing Higher Surface Area Metal–Organic Frameworks: Are Triple Bonds Better Than Phenyls?

We have synthesized, characterized, and computationally
validated
the high Brunauer–Emmett–Teller surface area and hydrogen
uptake of a new, noncatenating metal–organic framework (MOF)
material, NU-111. Our results imply that replacing the
phenyl spacers of organic linkers with triple-bond spacers is an effective
strategy for boosting molecule-accessible gravimetric surface areas
of MOFs and related high-porosity materials.

我们对一种新型非互穿金属有机框架（metal–organic framework, MOF）材料NU-111完成了合成、表征与计算验证，证实其拥有较高的布鲁诺尔-埃米特-泰勒（Brunauer–Emmett–Teller, BET）比表面积与氢气吸附容量。本研究结果表明，将有机配体中的苯基间隔基替换为三键间隔基，是提升金属有机框架及相关高孔隙率材料的分子可及重量比表面积的有效策略。
