有机染料和颜料构成了一大类工业产品。综述了这些化合物在有机电子领域的应用，尤其着重于有机场效应晶体管。结果表明，对于大多数主要类别的工业染料和颜料，即，酞菁，二萘嵌苯和萘二酰亚胺，二酮吡咯并吡咯，靛蓝和isoindigos，方酸，和部花青，电荷流子迁移率的超过1厘米² V ^-1小号^-1已实现。由于其n通道操作而研究最广泛的分子是per和萘二酰亚胺，其偶数值接近10 cm ² V ^-1 s ^-1已经证明。所有这些π共轭着色剂均包含导致强四极或什至偶极分子的极性取代基这一事实表明，与传统上在该领域中考虑的相比，实际上更大的结构空间显示出有机半导体分子设计的希望。特别是，由于许多这些染料和颜料生色团在其最初的染色和印刷应用中均表现出出色的热和（光）化学稳定性，并且可以通过简单的合成规程获得，因此它们在该领域的商业应用具有特别高的潜力电子产品。

Organic Semiconductors based on Dyes and Color Pigments

Organic dyes and pigments constitute a large class of industrial products. The utilization of these compounds in the field of organic electronics is reviewed with particular emphasis on organic field‐effect transistors. It is shown that for most major classes of industrial dyes and pigments, i.e., phthalocyanines, perylene and naphthalene diimides, diketopyrrolopyrroles, indigos and isoindigos, squaraines, and merocyanines, charge‐carrier mobilities exceeding 1 cm² V⁻¹ s⁻¹ have been achieved. The most widely investigated molecules due to their n‐channel operation are perylene and naphthalene diimides, for which even values close to 10 cm² V⁻¹ s⁻¹ have been demonstrated. The fact that all of these π‐conjugated colorants contain polar substituents leading to strongly quadrupolar or even dipolar molecules suggests that indeed a much larger structural space shows promise for the design of organic semiconductor molecules than was considered in this field traditionally. In particular, because many of these dye and pigment chromophores demonstrate excellent thermal and (photo‐)chemical stability in their original applications in dyeing and printing, and are accessible by straightforward synthetic protocols, they bear a particularly high potential for commercial applications in the area of organic electronics.
