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 1H 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) cm2/Vs and on/off ratio of 10(5).
通过铃木交叉偶联反应合成了三种新的蒽衍生物，即2,6-双(4-癸基苯基)蒽(DDPAnt)、2-癸基-5-(2-(5-癸基噻吩-2-基)蒽-6-基)噻吩(DDTAnt)和2,6-双(4-癸氧基苯基)蒽(DDPXAnt)。通过1H NMR、FT-IR、质谱、紫外可见光谱、循环伏安法、差示扫描量热法和热重分析对所得低聚物进行了表征。热学研究表明，这些低聚物在高达400℃时是稳定的。采用旋涂和滴铸工艺，在Si/SiO2上使用合成的低聚物制备了溶液处理的有机薄膜晶体管(OTFT)。基于DDPAnt的OTFT显示出7.6×10(-3)cm2/Vs的迁移率和10(5)的开/关比。
