Benzobisazoles as modular building blocks for novel organic electronic materials. We aim to prepare new conjugated building blocks by introducing subs7tuents across the central benzene ring of the benzo[1,2-‐d; 4,5-‐d'] bisoxazole moiety. The energy levels and band gaps of these materials are readily tuned via chemical synthesis making this a versa7le plaIorm for the development of new organic semiconductors.
