Hello dear, the unique interaction type is trough hydrogen bond, because this group is not reactive.
Dear Shu,
Isoindigo is an electron-deficient acceptor and can undergo polymirization when reacted with 3,4-ethylenedioxythiophene as the electron-rich donor. However, the polymirization reaction occurs on its phenyl ring and there is no direct role to the amide carbonyl group in the polymirization,

Hi Shu,
Actually, it's not the keto group on isoindigo. It is amide (lactam) -CONH group, which makes it less reactive.
