| 摘 要： | 由于缺乏可控的成膜技术,三亚苯类金属有机框架(MOFs)材料的应用受到了限制。我们在气液界面组装了不同厚度的Ni3(HITP)2薄膜(HITP3-=2,3,6,7,10,11-六亚氨基三亚苯),并将制备的薄膜转移到导电玻璃表面。利用X射线衍射(XRD)、场发射透射电子显微镜(FETEM)、场发射扫描电镜(FESEM)、X射线光电子能谱(XPS)和拉曼光谱对样品的晶体结构、微观形貌和元素组成进行表征,采用紫外可见分光光度计以及电化学工作站对Ni3(HITP)2薄膜的电化学和电致变色性能进行了研究和表征。结果表明,得益于Ni3(HITP)2电致变色薄膜的多孔结构和与电解液良好的接触,所得薄膜电极N-20具有较短的着色响应时间/褪色响应时间(0.6/0.7 s),且着色效率可达530 cm2·C-1;而N-50具有较大的光调制范围(740 nm,70%)。

| Abstract: | The lack of controllable film-forming technology limits the further application of triphenylene-based metal-organic frameworks (MOFs). In this work, the gas-liquid interface assembled Ni3(HITP)2 films (HITP3-=2,3,6,7,10, 11 hexaiminotriphenylene) with different thicknesses were transferred on the conductive glass. X-ray diffraction (XRD), field emission transmission electron microscope (FETEM), field emission scanning electron microscope (FESEM), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy were used to characterize the crystal structure, element composition and microscopic morphology of the samples. The electrochemical and electrochromic properties of Ni3(HITP)2 thin film were further studied and characterized. The results show that the Ni3(HITP)2 electrochromic film with porous structure and large specific surface area can increase the contact area with the electrolyte. Thus, the obtained film N-20 had short coloring/bleaching time (0.6/0.7 s) and high coloration efficiency (530 cm2·C-1), while N-50 had a large optical modulation range (70% at 740 nm). |
