Organic small molecular semiconductors have attracted much attention for their potential applications in organic field effect transistors (OFETs) for memory devices, smart cards, radio frequency identification tags, electronic papers, flexible displays and sensors. Among these, solution-processable small molecules with high performance and ambient stability are of great interest due to their possibility of a low-cost solution process and high flexibility in molecular design/modification for various OFETs applications. In my presentation, three series of small molecules, p-type compounds with 3,3’-dithioalkyl-2,2’-bithiophene (SBT) and 3,5-dithioalkyl dithienothiophene (DSDTT) based-small molecules and n-type quinidal dithioalkyterthiophene (DSTQ) compounds will be repoerted. These results indicate that OFETs semiconducting materials can be modulated through successive changes in conjugation length/side chain substituent length and molecular interaction, based on a combination of molecular design and solution-processing technique. |
