This work refers to the manufacture and characterization of organic electronic devices made from seven-coordinated diorganotin(IV) complexes and the polymer poly(3,4-ethylenedyoxithiophene)-poly(styrene sulfonate) (PEDOT:PSS). In order to obtain the best electronic behavior, the devices were manufactured by spin-coating with seven-coordinated diorganotin(IV) complexes, synthetized with different peripheral substituents. The modification of the polarity in the molecule, from the presence of the different functional groups, is used as a way to enhance the charge transport inside the devices. Additionally, the devices received a post-treatment with isopropyl alcohol, in order to change the structure of PEDOT:PSS from benzoid form to quinoid form. The electric charge transport was evaluated from the current density–voltage characteristics, under dark and illuminated conditions. The devices present a mobility of ∼10 −9 cm 2 /Vs decreasing to values of ∼10 −11

具有七配位二有机锡（IV）配合物和PEDOT：PSS结构改性的薄膜的生长，用于电子应用

这项工作涉及由七配位的二有机锡（IV）配合物和聚合物聚（3,4-乙撑二氧噻吩）-聚（苯乙烯磺酸盐）（PEDOT：PSS）制成的有机电子器件的制造和表征。为了获得最佳的电子性能，通过旋涂由七配位的二有机锡（IV）配合物合成的器件，这些配合物由不同的外围取代基合成。由于存在不同的官能团，分子中极性的改变被用作增强器件内部电荷传输的一种方式。另外，为了将PEDOT：PSS的结构从苯甲酸酯形式更改为醌型形式，设备接受了异丙醇的后处理。根据电流密度-电压特性评估了电荷传输，在黑暗和光照条件下。器件的迁移率约为10 -9 cm 2 / Vs，下降到约为-10 -11
