Hybrid ladder polymers containing Tröger's base (TB) and diazacyclooctane (DACO) units in the main chain with various contents of DACO unit were systematically synthesized by sequential post-polymerization modification including N-methylation and alkaline hydrolysis of TB-based ladder polymers to investigate the effect of DACO content on the thermal and gas adsorption properties of the hybrid ladder polymers. Notably, the presence of DACO unit improves the adsorption selectivity of CO₂ against N₂ compared with an original TB-based ladder polymer, while the TB/DACO hybrid ladder polymers partly maintain their intrinsic microporosity.

封面：Tröger 碱/二氮杂-环辛烷杂化梯形聚合物的热和气体吸附特性 (ChemNanoMat 7/2021)

通过顺序聚合后改性（包括TB 基梯形聚合物的N-甲基化和碱水解），系统合成了在主链中含有 Tröger 碱（TB）和二氮杂环辛烷（DACO）单元的杂化梯形聚合物，并具有不同含量的 DACO 单元。DACO 含量对杂化梯形聚合物的热和气体吸附性能的影响。值得注意的是，与原始的基于 TB 的梯形聚合物相比，DACO 单元的存在提高了 CO ₂对 N ₂的吸附选择性，而 TB/DACO 杂化梯形聚合物部分保持了其固有的微孔性。更多信息可以在 Fumitaka Ishiwari、Takanori Fukushima 等人的全文中找到。
