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.
