迄今为止,所有已知的空心笼状分子多少总含有碳分子。但是最近材料科学家发现了一种不含碳原子的二硫化钨笼状分子。这种无机半导体分子也会卷曲而形成圆柱形或封闭的多面体结构(图1,2)。以色列科学家R.坦纳及其同事已研制成功了长度不足10纳米到100纳米以上的微管,还有各种不同尺寸的笼。因为这种二硫化钨晶体是一个无机笼,它可能有与富勒烯不同的 To date, all known hollow cage molecules always contain carbon molecules. Recently, however, material scientists discovered a cage of tungsten disulfide molecules that contain no carbon atoms. Such inorganic semiconductor molecules also curl to form a cylindrical or closed polyhedral structure (FIGS. 1 and 2). Israeli scientist R. Tanner and his colleagues have developed microtubules less than 10 nanometers to 100 nanometers in length, as well as cages of various sizes. Because this tungsten disulfide crystal is an inorganic cage, it may differ from fullerenes
