将单体二苯二亚胺单元连接起来形成二聚体和三聚体，极大地增加了向列型液晶主体中的排列。通过柔性交联剂连接单元破坏了对齐：刚性交联器是必要的。在可切换窗口中应用荧光三聚体染料极大地提高了这种发电装置的开和关状态之间的对比度。
Linking monomeric perylenebisimide units to form dimers and trimers dramatically increased alignment in a nematic liquid crystalline host. Connecting units via flexible cross-linkers destroyed alignment: a rigid linker is necessary. Applying the fluorescent trimer dye in a switchable windowgreatly improved the contrast ratio between the 'on' and 'off' states of this energy generating device.
