共价有机骨架被设计成具有不同但离散含量的三芳胺单元的主链，这些三芳胺单元与CO2弱相互作用。吸附实验表明，三芳胺单元在 CO2 吸附过程中占主导地位，CO2 吸收量随三芳胺含量单调增加。这些深远的集体效应揭示了设计二氧化碳捕获和分离骨架的原则。
Covalent organic frameworks are designed to have backbones with different yet discrete contents of triarylamine units that interact weakly with CO2. Adsorption experiments indicate that the triarylamine units dominate the CO2 adsorption process and the CO2 uptake increases monotonically with the triarylamine content. These profound collective effects reveal a principle for designing backbones targeting for CO2 capture and separation.
