Pitfalls in the synthesis of polyimide-linked two-dimensional covalent organic frameworks

The well-known reaction of amines with carboxylic acid anhydrides to produce highly stable imide moieties has been extended in the literature to the synthesis of two dimensional polyimide-linked covalent organic frameworks (2D-COFs). We report a detailed study of these reactions to determine whether the reported polymerizations are producing the reported COFs. The studies include variations of reaction temperature, time, heating method, and monomer structures to establish whether formation of ordered crystalline material is occurring. The results of these studies indicate that a specific, previously reported polyimide COF is likely not produced with the order or exact structure as reported.

Cycloaddition approach to the curing of polyimides via precursor containing thiophene-S,S-dioxide

A new method for linear polymerization of maleimides via the Diels-Alder reaction has been developed. This method involves use of a new cross-linking agent, benzene-3,4-dimethylenesuccinimide, which can be generated in situ from its thiophene precursor, benzene-2,5-dihydrothiophene-3,4dicarboximide-S,S- dioxide. This new cross-linking agent is reasonably reactive, readily prepared, and stable at room temperature. A controlled molecular weight oligomer has been synthesized and applied to the polymerization to yield a highly thermal stable polyimide.
