与自上而下的纳米片（如石墨烯和金属硫属化物）相比，通过开发自下而上的聚合策略，可以获得二维聚合物纳米片的更大的结构通用性。然而，通过溶液聚合的合理合成一直是一个长期的挑战。考虑到Glaser偶联反应是由亚铜（I）盐在氧气的参与下催化的，设计了一种气/液界面偶联反应，并用于制备二维多孔三蝶烯基聚合物纳米片（2D-PTNS）。该2D-PTNS在常温常压下具有较高的比表面积、良好的气体吸附能力和对C2 H6/CH 4的选择性吸附。
The greater structural versatility of two-dimensional polymeric nanosheets could be available through the development of a bottom-up polymerization strategy compared with top-down nanosheets (such as graphene and metal chalcogenides). However, rational synthesis by solution polymerization has been a long-standing challenge. Considering that Glaser coupling is catalyzed by cuprous (I) salts with the participation of oxygen, an air/liquid interfacial coupling reaction has been designed and used to prepare a two-dimensional porous triptycene-based polymeric nanosheet (2D-PTNS). This 2D-PTNS shows a high BET surface area, good gas adsorption ability and excellent selective adsorption of C2H6/CH4 at ambient temperature and pressure.
