Organic semiconductor based on asymmetric naphthalene-thiophene molecule for organic thin film transistor

The new asymmetric semiconductor 5-(6-decylnaphthalen-2-yl)-5'-(naphthalene-2-yl)-2,2'-bithiophene (NBTND) was synthesized by Suzuki coupling reaction for an organic thin film transistor (OTFT) material. This asymmetric molecule was characterized by H-NMR, IR, HRMS, UV-visible spectroscopy, cyclovoltammetry, thermogravimetric analysis, differential scanning calorimetry. The thin film transistor using new asymmetric semiconductor exhibited the field effect mobility of 2.68 x 10(-2) cm2 V(-1) s(-1).
