Integration of metal-organic frameworks (MOFs) as components of advanced electronic devices is at a very early phase of development and the fundamental issues related to their crystal growth on conductive substrate need to be addressed. Herein, we report on the structural characterization of a newly synthesized Sr-based MOF {[Sr(2,5-Pzdc)(H O) ] ⋅ 3 H O} (1) and the uniform crystal growth of compound 1 on a conducting glass (fluorine doped tin oxide (FTO)) substrate using electrochemical deposition techniques. The Sr-based MOF 1 was synthesized by the reaction of Sr(NO ) with 2,5-pyrazinedicarboxylic acid dihydrate (2,5-Pzdc) under solvothermal conditions. A single-crystal X-ray diffraction analysis revealed that 1 has a 3D structure and crystallizes in the triclinic P space group. In addition, the uniform crystal growth of this MOF on a conducting glass (FTO) substrate was successfully achieved using electrochemical deposition techniques. Only a handful of MOFs have been reposed to grown on conductive surfaces, which makes this study an important focal point for future research on the applications of MOF-based devices in microelectronics.
将金属有机框架（MOF）作为先进电子器件的组件进行集成尚处于非常早期的发展阶段，与它们在导电衬底上的晶体生长相关的基本问题需要得到解决。在此，我们报道了一种新合成的基于Sr的MOF{[Sr(2,5-Pzdc)(H₂O)₂]⋅3H₂O}(1)的结构表征，以及使用电化学沉积技术在导电玻璃（氟掺杂氧化锡（FTO））衬底上实现化合物1的均匀晶体生长。基于Sr的MOF 1是通过Sr(NO₃)₂与2,5-吡嗪二甲酸二水合物（2,5-Pzdc）在溶剂热条件下反应合成的。单晶X射线衍射分析表明，1具有三维结构，结晶于三斜P-1空间群。此外，使用电化学沉积技术成功地在导电玻璃（FTO）衬底上实现了这种MOF的均匀晶体生长。仅有少数MOF被报道能在导电表面生长，这使得本研究成为未来基于MOF的器件在微电子学中应用研究一个重要的焦点。
