Twisted Aromatic Frameworks: Readily Exfoliable and Solution‐Processable Two‐Dimensional Conjugated Microporous Polymers

Twisted two‐dimensional aromatic frameworks have been prepared by overcrowding the nodes with bulky and rigid substituents. The highly distorted aromatic framework with alternating out‐of‐plane substituents results in diminished interlayer interactions that favor the exfoliation and dispersion of individual layers in organic media. A twist of fate! A twisted two‐dimensional aromatic framework was prepared by overcrowding the nodes with bulky and rigid substituents (see structure). The highly distorted aromatic framework with out‐of‐plane substituents results in diminished interlayer interactions, thus favoring the exfoliation and dispersion of individual layers in organic media.
