a Molecular structure puzzle of 12 polymers. We split the molecular structure into nine structural units, i.e., amino, p-benzene, ether, anhydride, m-benzene, cyclohexane, o-toluene, methylene and isopropyl. b Comparison of electrical and thermal properties between polymers synthesized in this work, polymers reported previously and common commercial polymers (i.e., polyethylene glycol terephthalate (PET), polyethylene naphthalate (PEN), poly(ether-ether-ketone) (PEEK), and polyamide-imide (PAI)). c The contribution of each structural unit on the glass transition temperature and bandgap relative to the regular PI or PEI structure.
