Abstract: The unit-cell-size comparable ultrathin nanowires(UCNWs) with typical cross-sectional dimension of around one nanometer, comparable to the unit-cell-size of inorganic materials, exhibit unique properties different from traditional nanomaterials. However, their facile and general synthesis is still a great challenge, since it not only demands the anisotropic growth in one direction, but also needs to completely restrict the growth in the other two dimensions. In this review, we summarize and introduce a strategy to prepare UCNWs using nanoclusters as synthons, which is promising to be a general synthesis method for UCNWs. We start with the introduction to the definition and characteristics of UCNWs. Subsequently, the key problems of UCNWs synthesis are analyzed from the perspective of thermodynamics and the strategy of using nanoclusters as synthons is proposed. Then, the related works about synthesis of UCNWs using magic-size clusters(MSCs) and polyoxometalate(POM) clusters as synthons are introduced and carefully discussed. Finally, challenges and opportunities are also elaborately discussed. This review is anticipated to provide a panoramic sketch and future directions toward the general synthesis of UCNWs.
