Photoactive compounds for vapor deposition of organic photovoltaic devices

Photoactive compounds are disclosed. The disclosed compounds may exhibit molecular structure elements that tend to increase the evaporability or volatility of the compound, for example, by replacing a free rotating pendant group with a conformationally limited pendant group or replacing a dicyanomethylene indanone moiety with an indandione moiety to include geometric core disruption. The disclosed photoactive compounds include those having imine-bridged linking moieties that can convert optical properties to more redshifted absorption compared to linking moieties having olefin-bridged linking moieties. The disclosed photoactive compounds are useful in organic photovoltaic devices, such as visible light transparent or opaque photovoltaic devices. 公开了光活性化合物。所公开的化合物可以表现出倾向于增加化合物的蒸发性或挥发性的分子结构元素，这例如通过使用在构象上受限的侧基代替自由旋转的侧基或使用茚满二酮部分代替二氰亚甲基茚满酮部分以包括几何核破坏来实现。所公开的光活性化合物包括具有亚胺桥联的连接部分的那些化合物，与具有烯烃桥联的连接部分相比，亚胺桥联的连接部分可以将光学性质转变为更红移的吸收。所公开的光活性化合物可用于有机光伏器件，例如可见光透明或不透明的光伏器件。
