Abstract:
In an embodiment, a composition is provided that includes an indenofluorene moiety; an alkyl radical, an aryl radical, or a heteroaryl radical chemically bound to the indenofluorene moiety; and an electron donor moiety bound to the indenofluorene moiety. In another embodiment, a device is provided that includes compositions described herein. In another embodiment, a method of forming a donor-acceptor small molecule or a donor-acceptor copolymer is provided that includes forming an indenofluorene moiety; forming an electron donor moiety; and reacting the indenofluorene moiety with the electron donor moiety in a cross-coupling reaction.
