A carbonyl-functionalized indole-based microporous organic polymer (PKIN) was designed and synthesized in the presence of the FeCl₃ catalyst by a facile direct oxidative coupling reaction. Taking advantage of the synergistic effect of indoles and their adjacent carbonyl moieties on carbon dioxide (CO₂), the CO₂ uptake capacity of the polymer reaches up to 6.12 mmol g⁻¹ (1.0 bar, 273 K) with high gas selectivities, making the polymer a promising microporous material for the application of CO₂ separation and capture, and the proposed synergistic effect is expected to be a new rationale for the design of CO₂ capture materials.

通过吲哚及其相邻羰基的协同作用，提高了基于吲哚的微孔有机聚合物中的二氧化碳捕获能力†

在FeCl ₃催化剂存在下，通过简单的直接氧化偶联反应设计并合成了羰基官能化的基于吲哚的微孔有机聚合物（PKIN）。利用吲哚及其相邻的羰基部分对二氧化碳（CO ₂）的协同作用，在高气体选择性的情况下，聚合物的CO ₂吸收容量达到了6.12 mmol g ^-1（1.0 bar，273 K），该聚合物是用于CO ₂分离和捕获的有前景的微孔材料，预期的协同作用有望成为设计CO ₂捕获材料的新原理。
