Finally, the concept of the amorphous side chain poly(triarylamines) was further extended to segments carrying TPDs. In general, the charge carrier mobility of TPDs is expected to be superior compared to simple TPAs [54, 55]. Two methoxy-groups were introduced to the TPD unit in the 4-position for the sake of solubility. 

However, another approach for improving the charge carrier mobility is to employ conjugated, semi-crystalline polymers. Here, a further advantage is the extended absorption in the visible range. These issues are addressed in the next chapter which is concerned with crystalline-crystalline block copolymers comprised of poly(3-hexythiophene) and PPerAcr. 

Poly(2,5-bis(3-alkylthiophen-2-yl)thieno(3,2-b)thiophenecopolymers (pBTTT) were reported [50] with high charge carrier mobilities. This has been attributed to the large crystalline domains formed by the assembly of the planar conjugated backbones into closely pi-stacked sheet-like lamellae, and subsequent orientation of these domains in the plane of the substrate, hence... 

Thin film field-effect transistors have been prepared of poly(3-alkyl-thiophenes) by using spin-coating techniques. The devices are used in the determination of the charge carrier mobility p, dc conductivity a, and the carrier concentration p. Poly(3-hexylthiophene) is characterized in a wide temperature range T = 130 - 430 and possible transport mechanisms are discussed. ... 

The charge carrier mobility of organic semicondnctors is much lower than that of crystalline silicon. However, valnes associated with amorphous silicon (a-Si) have already been achieved, and it is expected that valnes will continue to improve until those of polycrystalline silicon (poly-Si) are reached (see Figure 1.3). This will be... 

Figure 1.3 OE-A roadmap for the charge carrier mobility of semiconductors for organic electronics applications. The values refer to materials that are available in commercial quantities and to devices that are manufactured in high throughput processes. The values for amorphous silicon (a-Si) and polycrystalline silicon (poly-...
