A pi-electronic covalent organic framework catalyst: pi-walls as catalytic beds for Diels-Alder reactions under ambient conditions

摘要

We report a strategy for developing pi-electronic covalent organic frameworks as heterogeneous catalysts that enable the use of columnar pi-walls as catalytic beds to facilitate organic transformations in their one-dimensional open channels. The pi-frameworks exhibit outstanding catalytic activity, promote Diels-Alder reactions under ambient conditions and are robust for cycle use.
