通过自下而上的方法合成了包含平面镍双（二硫杂环戊烯）络合物的π共轭纳米片。使用苯六硫醇在有机相中和乙酸镍（II）在水相中的液-液界面反应产生具有几微米厚度的半导体块状材料。粉末X射线衍射分析显示，块状材料的结晶部分包括纳米片的交错堆叠。利用气液界面反应成功地制备了单层纳米片。原子力显微镜和扫描隧道显微镜证实了π共轭纳米片是单层的。使用化学氧化还原反应可以调节纳米片的氧化态。
A pi-conjugated nanosheet comprising planar nickel bis(dithiolene) complexes was synthesized by a bottom-up method. A liquid-liquid interfacial reaction using benzenehexathiol in the organic phase and nickel(II) acetate in the aqueous phase produced a semiconducting bulk material with a thickness of several micrometers. Powder X-ray diffraction analysis revealed that the crystalline portion of the bulk material comprised a staggered stack of nanosheets. A single-layer nanosheet was successfully realized using a gas-liquid interfacial reaction. Atomic force microscopy and scanning tunneling microscopy confirmed that the pi-conjugated nanosheet was single-layered. Modulation of the oxidation state of the nanosheet was possible using chemical redox reactions.
