摘要
二维层状材料的扭曲角和连续两层之间的晶格失配所带来的令人兴奋的电子特性已得到广泛认可。主要的挑战在于如何控制摩尔纹周期。在此,我们报告了一种化学定向方法,利用软键实现锌离子和邻苯二甲酸复合物组装所需的摩尔纹周期精度。邻苯二甲酸与锌离子在水介质中于 80 °C 下反应 1 小时,然后将反应混合物保存在环境温度(35 °C)下,可产生具有精确周期的平移摩尔超晶格。这些晶格在角度上进一步堆叠,就得到了旋转超莫埃晶格。此外,通过与 8-羟基喹啉-5-磺酸(HQS)的反应,研究了 π-锌离子相互作用在摩尔条纹起源中的作用,也确定了超晶格的可逆性。目前的观察结果还表明,摩尔纹超晶格是通过离子插入化学晶格而形成的。
Chemically Reversible Translational Moiré Superlattice Formations in the Two-Dimensional Films of the Zinc Phthalate Complex
The exciting electronic properties of two-dimensional layered materials introduced by twist angle and lattice mismatch between two consecutive layers are well-recognized. The major challenge lies in the control over the moiré periodicity. Herein, we report a chemically directed way to achieve the desired precision over moiré periodicity of the assembly of a complex of zinc ions and o-phthalic acid utilizing soft bonds. The reaction of o-phthalic acid with zinc ions in the aqueous medium at 80 °C for 1 h followed by preserving the reaction mixture at ambient temperature (35 °C) resulted in translational moiré superlattices with precise periods. Those lattices are further stacked angularly to give rotational super-moiré lattices. Further, the role of the π–zinc ion interaction in the origin of moiré fringes was examined with the reaction with 8-hydroxyquinoline-5-sulfonic acid (HQS) that also established the reversible nature of the superlattices. The present observations also suggest the formation of moiré superlattice through ion insertion in a chemical lattice.
期刊介绍:
The Journal of Physical Chemistry (JPC) Letters is devoted to reporting new and original experimental and theoretical basic research of interest to physical chemists, biophysical chemists, chemical physicists, physicists, material scientists, and engineers. An important criterion for acceptance is that the paper reports a significant scientific advance and/or physical insight such that rapid publication is essential. Two issues of JPC Letters are published each month.
