| 摘要 |
Photoactive compositions of matter, methods for their design and synthesis, and various applications of such compositions of matter are disclosed. Such photoactive compositions may, for example, include any one or more of the following: a core moiety; a primary electron donor moiety; an electron-withdrawing moiety; and an alkyl tail. Some photoactive compositions may further include multiple additional electron donor moieties, electron-withdrawing moieties, and alkyl tails. Applications of such photoactive compositions of matter may include use in photovoltaic cells (e.g., as a p- or n-type material of the active layer of some photovoltaic cells, or as a dye to be employed in other photovoltaic cells); batteries, field-effect transistors; and light-emitting diodes. |
