| Abstract |
New benzothiadiazole derivatives, 4,7-bis(5-phenylthiophen-2-yl)benzo[c][1,2,5]thiadiazole (PT-BTD) and 4,7-bis(4-(thiophen-2-yl)phenyl)benzo[c][1,2,5]thiadiazole (TP-BTD), were synthesized and characterized as small molecular organic semiconductors for organic thin-film transistors (OTFTs) and complementary inverters. Thermal, optical, and electrochemical properties of the new compounds were fully characterized. For the fabrication of thin films based on new compounds, vacuum deposition and solution-shearing method were employed. Thin films based on PT-BTD exhibited p-channel characteristics with hole mobility as high as 0.10 cm2 V-1 s-1 and current on/off ratio > 107 for top-contact/bottom-gate OTFT devices. With an optimized blending ratio of PT-BTD and the representative n-channel semiconductor, PDIFCN2, bulk heterojunction (BHJ) ambipolar transistors were fabricated with balanced hole and electron mobility of 0.10 and 0.07 cm2 V-1 s-1, respectively. Furthermore, a complementary-like inverter using ambipolar thin-film transistors was fabricated, which showed high voltage gain of 84. |
