- Abstract
- Three new anthracene derivatives, 2,6-bis(4-decylphenyl)anthracene (DDPAnt), 2-decyl-5-(2-(5-decylthiophen-2-yl)anthracen-6-yl)thiophene (DDTAnt), and 2,6-bis(4-decyloxy phenyl) anthracene (DDPXAnt) were synthesized by Suzuki cross-coupling reaction. The obtained oligomers were characterized by H-1 NMR, FT-IR, Mass, UV-visible spectroscopy, cyclovotammetry, differencial scanning calorimetry, and thermogravimetric analysis. The thermal studies show that these oligomers are stable up to 400 degrees C. The solution processed OTFTs were fabricated using synthesized oligomers by spin-coating and drop casting processes on Si/SiO2. OTFTs based on DDPAnt showed the mobility of 7.6 x 10(-3) cm(2)/Vs and on/off ratio of 10(5).
