Oligothiophenes single crystals

Table 1. Comparative experimental structural data of non-substituted oligothiophenes single crystals.

Mobilities up to 1.5 cm2 V-1 s 1 have been obtained for films deposited on hcale substrates [94—96]. As in the case of oligothiophenes, this has been attributed to a highly ordered morphology, close to that of a single crystal [94]. However, high values are only obtained under very acute deposition parameters (in particular an opti... 

The performance of OFETs has continuously improved since they were first reported in 1987 [8, 9]. The rate of the progress can be visualized in Figure 14-13, where we have plotted the field-effect mobility of five prominent organic com-pounds as a lunclion of the publication date. The data include one polymer, polythiophene and its derivatives and four small molecules (three oligothiophenes, plus pentacene). Note that the highest mobility of small molecules was reported on single crystals. 

Structure and Properties of Oligothiophenes in the Solid State Single Crystals and Thin Films... 

The aim of this chapter is to review the structure and properties of solid state oligothiophenes, particularly single crystals and vacuum-deposited thin films. Particular attention is given to the influence of chain length and substitution keeping in mind their potential applications in electronic devices.
