摘要: Vacuum carbonization of organic precursors usually causes considerable structural damage and collapse of morphological features. However, for a polymer with intrinsic microporosity (PIM-EA-TB with a Brunauer–Emmet–Teller (BET) surface area of 1027 m²g–¹), it is shown here that the rigidity of the molecular backbone is retained even during 500° C vacuum carbonization, yielding a novel type of microporous heterocarbon (either as powder or as thin film membrane) with properties between those of a conducting polymer and those of a …
