An oligomer semiconductor with an asymmetric cyclohexylhexyl end group for solution-processed organic field-effect transistors

다국어 초록 (Multilingual Abstract)

<P><B>Abstract</B></P> <P>We report on the synthesis of an oligomer semiconductor, 2-(6-((6-cyclohexylhexyl)oxy)naphthalen-2-yl)anthracene (C-HNA), and research its potential application as a thin-film active layer for organic field-effect transistors (OFETs). The measured field-effect mobility of the spin-coated C-HNA films for OFETs was 2.3 × 10<SUP>−2</SUP> cm<SUP>2</SUP>/(V·s). The performance of the resulting OFETs was attributed to the packing tendency of the asymmetric oligomer, where the asymmetric cyclohexylated alkyl chains were vertically aligned to the substrates, which contributed to favorable charge transfer.</P> <P><B>Highlights</B></P> <P> <UL> <LI> An asymmetric oligomer semiconductor is synthesized for organic electronics. </LI> <LI> The crystalline semiconductor film is successfully formed from the synthesized oligomer. </LI> <LI> The OFETs with the oligomer exhibited fairly good performances. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
