- Abstract
- Quinoidal molecules have aroused great interest as a promising active layer for OFETs
because of their unique advantages, which is beneficial for rigid and planar structure.
In addition, they show the extended π-conjugation length resulting from the overlapping
pz-orbitals. They can therefore induce the favorable charge transport path. However,
since quinoidal molecules have the difficulty in purifying unavoidable geometric isomers
during synthesis, studies on these molecules are relatively rare. We designed and
synthesized the quinoidal monomer (QEDOT) with isomer-free. Finally, QEDOT was
polymerized with spacers of thiophene, bithiophene and thienylene vinylene. In this
study, As spacers are incorporated, quinoidal polymers showed the change of molecular
orientation from bimodal and edge-on, resulting in the different charge transport property.
The quinoidal polymers were systemically characterized with various measurements.
