Student thesis: Doctoral Thesis


At the beginning, a brief overview of two-dimensional materials as well as an introduction of the organic metal complex nanosheets was presented in chapter 1. In this section, the attention was mainly focused on the concept of the 2D nanomaterial, including the design strategies, the categories, the synthetic approaches and the characterization methods. Also, the materials used as electrodes of batteries for energy storage were generally introduced. Those electroactive materials were classified according to their different functional mechanism. The opportunity and challenge of this kind of electroactive materials were then demonstrated. At last, the current development of the 2D materials as electrodes, including the typical structures and the superiority, was indicated.;A brand-new symmetric four-way terpyridine derivative (1,2,4,5-tetrakis(4-(2,2':6',2"-terpyridyl)phenyl)benzene) (L7) was then designed and coordinated with Co(II) ion to assemble a novel bottom-up multilayer nanosheet 7-Co in chapter 4. The generated nanosheet featured moderate mechanical strength and insolubility in both aqueous solution and organic solvent, which can facilitate the purification and collection of the product. By taking the advantages of the reversible and robust redox activity of Co2+/Co3+, a dual-ion battery cathode was achieved by employing the 7-Co and thus it reveals the possibility of this kind of metal organic complex nanosheet to be utilized in a battery.;1.7\xFinally, the findings, analysis results and future work were concluded in chapter 6. And the experimental details were described in chapter 7
