已经开发了许多剥离策略来从单晶制备2-D片材。然而，大多数已发表的研究都使用了微尺度晶体。大块晶体向微米或纳米尺度结构的转变很少通过化学蚀刻实现。我们在这里报告的制备四硫富瓦烯（TTF）接枝钛氧簇（TiO TTF），可以很容易地剥离在毫米级。这是第一个钛氧簇与TTF部分成功结合的例子。在氧气气氛中，TiO-TTF簇的红色晶体变为由规则排列的地板状微板组成的黑色“晶体”。该材料的剥离性能是TTF基团的易氧化性和TiO簇的催化性能的结果。团簇中的TTF基团不仅是一个氧化中心，而且为TiO材料增加了新的光电活性。观察到TiO-TTF和TiO-TTF（+）材料的增强的光电流响应。
Many exfoliation strategies have been developed to prepare 2-D sheet materials from single crystals. However, most of the published research has used micro-scale crystals. The transformation of bulk crystals to micro- or nano-scale structures has rarely been achieved by chemical etching. We report here the preparation of a tetrathiafulvalene (TTF)-grafted titanium-oxo-cluster (TiO–TTF) that can be easily exfoliated at a millimeter scale. This is the first example of a titanium-oxo-cluster successfully combined with a TTF moiety. In an oxygen atmosphere, the red crystal of the TiO–TTF cluster changes to a black ‘crystal’ composed of regularly arranged floorboard-like micro-plates. The exfoliation properties of the material are a result of the easy oxidation of the TTF group and the catalytic properties of the TiO cluster. The TTF moiety in the cluster is not only an oxidation center, but also adds new photoelectroactive properties to the TiO material. An enhanced photocurrent response was observed for the TiO–TTF and TiO–TTF(+) materials.
