Force-responsive ordered carbonaceous frameworks (OCFs) are synthesized for the first time. Carbonization of Ni porphyrin monomers having eight polymerizable ethynyl groups yields OCFs with atomically dispersed divalent Ni species and developed micropores. The highest specific surface area (673 m g) among the OCFs has been achieved. The OCFs thus synthesized comprise non-stacked graphene sheets, affording a unique mechanical flexibility that enables force-driven reversible phase transition.
首次合成了力响应有序碳质骨架(OCFs)。具有八个可聚合乙炔基的镍卟啉单体碳化后产生具有原子分散的二价镍物种和发达微孔的OCFs。已实现了OCFs中最高的比表面积(673 m²/g)。如此合成的OCFs由未堆叠的石墨烯片组成,具有独特的机械柔韧性,能够实现力驱动的可逆相变。
