Conjugated Polymers from Acenaphthene imide and Acenaphthylene imide: Significant Modulation of Optoelectronic Properties by Different Fused-Pentagon Rings

A novel family of π-extended strong acceptor units, i.e., dibrominated acenaphthene imide derivatives (ANI-2Br), are synthesized by form dehydrogenation of the saturated fused-pentagon rings in the dibrominated acenaphthylene imide precursors...
