Abstract

We report the first successful green synthesis route for organic transistors based on para-aminobenzoic acid (PABA) grafted to ferrite nanoparticles, at room temperature. The obtained core–shell nanoparticles (NCS) have been investigated by DLS, FT-IR, SEM, TEM. Both average hydrodynamic diameter and zeta potential of synthesized PABA-NCS nanoparticles has been identified, indicating a good stability of this nano-compound. SEM analysis proved a heterogeneous structured material with quasi-uniform granular formations in size, while TEM revealed a ferrite core of 20 nm. The measurements of output characteristics in the saturation regime and transfer characteristics at negative gate voltages have proved that an organic transistor based on PABA-NCS has been accomplished. The current increasing over a negative threshold voltage demonstrated an accumulation channel onset in the PABA-NCS thin film. This is a final argument for the p-type behavior of the PABA-NCS film.

绿色有机薄膜晶体管的解决方案：具有PABA外壳作为p型膜的Fe 3 O 4纳米核

摘要

我们报告了在室温下基于对氨基苯甲酸（PABA）接枝到铁氧体纳米粒子的有机晶体管的第一个成功的绿色合成路线。通过DLS，FT-IR，SEM，TEM对获得的核-壳纳米粒子（NCS）进行了研究。已确定合成的PABA-NCS纳米颗粒的平均流体动力学直径和Zeta电位，表明该纳米化合物具有良好的稳定性。扫描电镜分析证实了一种异质结构的材料，其尺寸具有准均匀的颗粒形式，而透射电镜则显示了20 nm的铁氧体磁心。在饱和状态下的输出特性和负栅极电压下的传输特性的测量证明，已经完成了基于PABA-NCS的有机晶体管。在负阈值电压之上增加的电流表明在PABA-NCS薄膜中出现了累积通道。这是对PABA-NCS膜的p型行为的最终论证。
