| Summary: | 碩士 === 國立中央大學 === 化學研究所 === 97 === Eight molecules based on DTT and TTA skeletons have been
synthesized. DTT system contains DFP-DTT (1), DTT-DTT (2),
DBT-DTT (3), DBF-DTT (4), DN-DTT (5), and FPP-DTT (6). TTA
system contains DP-TTA (7) amd DFP-TTA (8).
The device fabrications of all eight the materials are currently
assisted by Tobin J. Marks group at Northwestern University.
Asymmetric FPP-DTT (6), a P-type semiconductor, exhibits good
field-effect performance with a high mobility of 0.2 cm2/Vs. DFP-DTT
(1) exhibits N-type FET behavior with a mobility of 0.06 cm2/Vs.
DFP-TTA (8), a N-type semiconductor material, exhibits excellent
field-effect performance with a mobility as high as 0.3 cm2/Vs. These
organic semiconductor materials all show good stability under photo and
thermal conditions.
