通过湿化学方法合成了纳米尺寸且稳定的硫醇盐保护的钴簇，形成具有明确光学活性（紫外-可见）和光致发光的粉红色溶液。尺寸约 1.3 nm 的钴簇核是金属的（通过扫描透射电子显微镜、扫描隧道显微镜、X 射线光电子能谱、电子能量损失光谱表明），并被硫醇盐短钉的特定构型包围（根据拉曼光谱、傅里叶变换红外光谱、X 射线吸收精细结构、 基质辅助激光解吸电离）类似于相应的金簇。
Nanometer-sized and stable thiolate-protected cobalt clusters were synthesized by a wet chemical method, leading to a pink solution with well-defined optical activity (ultraviolet–visible) and photoluminescence. The cobalt cluster core of ∼1.3 nm size was metallic (as indicated by scanning transmission electron microscopy, scanning tunneling microscopy, X-ray photoelectron spectroscopy, electron-energy loss spectroscopy) and was surrounded by a specific configuration of thiolate staples (according to Raman spectra, Fourier transfrom infrared spectroscopy, X-ray absorption fine structure, matrix-assisted laser desorption ionization) that is similar to that of corresponding gold clusters.
