Novel oligomers based on P-substituted thiophene derivatives were synthesised with the aim to build-up a small molecule organic field-effect transistor (OFET). The developed material, a,o)-dicyano-P,P -dibutylquaterthiophene (DCNDBQT), exhibits exeellent thermal, optical and electrochemical stability.

The semiconductive properties of conjugated polymers are also exploited for application in thin-film organic field-effect transistors (OFETs). The earliest materials examined were polyacetylene [17], polythiophene [18], and an oligomer of thiophene [19]. In these...

The differences in the final properties of the copolymer according to the monomer s feed ratio were also observed for P(DHQT-co-DNBP) (12) films electrodeposited onto ITO/glass. DHQT is a fluorescent thiophene oligomer usually applied as active layer for assemble of organic field effect transistors (OFETs)/ photovoltaic cells and electrochromic devices/ while the polymer PDNBP and its copolymer with EDOT have... 

Abstract The main methodologies for the synthesis of fused thiophenes (thienothiophenes, dithienothiophenes, and thienoacenes) and some of their oligomers and polymers are described. Such compounds are particularly important in materials chemistry. They have applications in organic light-emitting diodes (OLEDs), organic field effect transistors (OFETs), (dye-sensitized) solar cells, and electrochromic devices (ECDs).
