Thieno[3,2-b]pyrrole is an effective nonconventional semiconducting building block that could be generated in gram quantities with relatively high overall yields. Three organic semiconductors containing thieno[3,2-b]pyrrole were synthesized in good yields without requiring time-consuming column purifications. The synthesis, optical and electrochemical properties were systematically investigated.1 Introduction2 Experimental3 Synthesis and Characterization4 Theoretical Calculations5 Optical and Electrochemical Properties6 Thermal Stability7 Fluorescence Experiments8 GIXRD Data9 Conclusions

AbstractOrganic semiconductors exhibiting complementary-type carrier mobility are the key components for the development of the field of “plastic electronics”. We present here a novel series of αω- and isomerically pure β,β'-diperfluorohexyl-substituted thiophene and study the impact of fluoroalkyl substitution and conjugation length vìs-à-vìs the corresponding fluorinefree analogues. Trends between the fluorinated and fluorine-free families in molecular packing, HOMO-LUMO gap, and π-π interactions are found to be strikingly similar. TFT measurements indicate that all members of the fluorinated series are n-type semiconductors

Electronic And Structural Properties

The synthesis of four N-functionalized bis[1]benzothieno[3,2-b:2′,3′-d]pyrroles (BBTPs) is reported in order to provide a more detailed characterization of these fused-ring units, as well as increase the scope of known BBTP units available for application to conjugated materials. The optical, electronic, and structural properties of the resulting BBTP units have been compared to the parent N-alkyl- and N-aryl-dithieno[3,2-b:2′,3′-d]pyrroles (DTPs), as well as their corresponding 2,6-diphenyl derivatives, in order to fully quantify the relative electronic effects resulting from benzannulation of the parent DTP building block. Such comparative analysis reveals that benzannulation results in a red-shifted absorbance, but to a lesser extent than simple phenyl-capping of the DTP. More surprising is that benzannulation results in stabilization of the BBTP HOMO, compared to the destabilization normally observed with extending the conjugation length of the backbone.
