An organometallic nickel complex containing thieno[3,2-]thiophene units was designed and synthesized. Composite films of the resulting nickel complex and polyvinylidene difluoride, which can be fabricated via a simple solution process under atmospheric conditions, exhibit remarkably high n-type conductivity (>200 S cm). Moreover, the thermoelectric power factor of the n-type composite film was proven to be air stable. A grazing-incidence wide-angle X-ray diffraction analysis indicated a significant impact of introducing the thieno[3,2-]thiophene core into the backbone of the nickel complex on the orientation within the composite films.
设计并合成了一种含有噻吩并[3,2 - b]噻吩单元的有机金属镍配合物。所得镍配合物与聚偏二氟乙烯的复合膜可在大气条件下通过简单的溶液法制备，具有显著的高n型导电性（>200 S cm⁻¹）。此外，n型复合膜的热电功率因子被证明具有空气稳定性。掠入射广角X射线衍射分析表明，在镍配合物主链中引入噻吩并[3,2 - b]噻吩核对复合膜内的取向有显著影响。
