TpPa-(NO2) COF

孔径	1.5nm
比表面	>300m2/g

荧光：无明显荧光；具有多种相互作用力，包括静电、极性、范德华力、氢键、疏水和C─Hσ-π相互作用 在水溶液中，在沸水（100°C）中放置7天，PXRD峰位置和强度不变；在12MHCl、2MH₂SO₄等强酸中浸泡1周以及在0.1MNaOH碱性水溶液中可保持24h稳定；热稳定性方面，在300°C稳定，失重不超过10%，350°C后开始分解； 气体吸附与分离：从C₂H₂/C₂H₄/CO₂混合物中选择性分离C₂H₄，从CO₂/N₂中捕获CO₂。 [1] Chemically Stable Multilayered Covalent Organic Nanosheets from Covalent Organic Frameworks via Mechanical Delamination. https://doi.org/10.1021/ja408121p
