TL;DR: Vapor-deposited thin films of a newly developed sulfur-containing heteroarene, 2,7-diphenyl[1]benzothieno[3,2-b][1] Benzothiophene (DPh-BTBT) showed excellent FET characteristics in ambient conditions with mobilities of approximately 2.0 cm2 V-1 s-1 and Ion/Ioff of 107.5 cm2.
Journal ArticleDOI
Functional oligothiophenes as advanced molecular electronic materials
TL;DR: In this paper, the porphyrin/oligothiophene/fullerene triad system is designed to evaluate efficient intramolecular electron transfer from the terminal porphrin to the other terminal fullerene through the central oligothiophenes.
Journal ArticleDOI
Synthesis and Spectroscopic Properties of a Series of β-Blocked Long Oligothiophenes up to the 96-mer: Revaluation of Effective Conjugation Length
TL;DR: A series of extraordinarily long oligothiophenes up to the 96-mer has been developed by iterative oxidative coupling of the completely beta-blocked sexithiophene.
Journal ArticleDOI
2,6-Diphenylbenzo[1,2-b:4,5-b']dichalcogenophenes: a new class of high-performance semiconductors for organic field-effect transistors.
TL;DR: All three benzodichalcogenophenes acted as good p-type semiconductors, and particularly the selenophene analogue, 2,6-diphenylbenzo[1,2-b:4,5-b']diselenophene, showed high FET mobility of 0.17 cm2 V-1 s-1.
Journal ArticleDOI
2,7-diphenyl[1]benzoselenopheno[3,2-b][1]benzoselenophene as a stable organic semiconductor for a high-performance field-effect transistor.
TL;DR: X-ray diffraction examination revealed that the diphenyl derivative DPh-BSBS formed a good thin film on the Si/SiO(2) substrate by vapor deposition, making it suitable for use in the fabrication of organic field-effect transistors (OFETs).
