Design and Synthesis of Novel Polyacenes and Applications in Organic Electronics
並列摘要
The electronics are surrounded in our lives. The interests of electronic materials have turned to organic materials for the possibility of making flexible, large area devices. We designed, synthesis organic materials based on polyacene skeleton and applied in organic field-effect transistors (OFET) and organic photovoltaic (OPV).We investigated the cycloaddition of hexacene with fullerene[60]. The products of this reaction were HC-1 and HC-2. With the addition of diiodooctane, the OPV quantum efficiency of HC-1can be promoted to 0.38%. The second part was synthesis of soluble hexacene precursor, 3-9 and applied in OFET. The mobility is 3.5 x 10-2 cm-2 V-1s-1, with Ion/Ioff 1 x 104 and a threshold voltage of -44 V.In the last part, we introduced furan into polyacene and synthesized 4-1aand4-1b. These compounds can be applied in both OFET and OPV. The OFET devices made with 4-1bhad a good hole mobility of0.11 cm2V-1s-1with an on/off ratio of 8.0x104 and undera threshold voltage of 18 V. The OPV performances were not satisfied due to poor morphology.
