Specific monomer sequences in aromatic copolyimides are recognized through their π‐stacking and hydrogen‐bonding interactions with a sterically and electronically complementary molecular tweezer. These interactions enable the tweezer molecule to “read” monomer sequences comprising up to 27 aromatic rings by multiple adjacent binding to neighboring sites on the polymer chain (see picture).
