已经在各种小分子材料中观察到双极晶体管特性。由于需要小的能隙，因此已经尝试了许多类型的分子设计，包括扩展的π骨架以及供体和受体单元的掺入。除了能级之外，惰性钝化层对于观察双极晶体管特性也很重要。双极输运已在特殊的π电子系统中观察到，例如反芳香族化合物、双自由基、自由基、金属配合物和氢键材料。一些供体/受体共晶也显示出双极传输。
Ambipolar transistor properties have been observed in various small-molecule materials. Since a small energy gap is necessary, many types of molecular designs including extended pi-skeletons as well as the incorporation of donor and acceptor units have been attempted. In addition to the energy levels, an inert passivation layer is important to observe ambipolar transistor properties. Ambipolar transport has been observed in extraordinary pi-electron systems such as antiaromatic compounds, biradicals, radicals, metal complexes, and hydrogen-bonded materials. Several donor/acceptor cocrystals show ambipolar transport as well.
