Novel Physical Properties based on Solid-state Protonics

在这项工作中，我们成功地利用金属离子和/或有机分子作为构建块，从下到上制备了定义良好的维度交叉纳米结构，具有高度的可调性。我们成功地合理地构建了长约2 nm的方形棱柱状金属-有机纳米管的组装。管内形成了均匀的一维通道，可以选择性地吸附H2O和乙醇。它的光学带隙约为半导体区的0.76 eV，X射线和理论研究揭示了它独特的CDW四重态电子结构。此外，它的电子态可以通过结构成分和客体分子的交换来连续控制。本文的结果展示了一条制造结构和电子态高度可调的纳米管的合理途径，也可能为多功能纳米材料的研究提供有价值的见解。

In this work, we have successfully archieved a bottom-up fabrication of well-defined dimensional-crossover nano-architectures with high tunability using metal ions and or­ganic molecules as building blocks. We succeeded in rationally constructing an assembly of square prism-shaped metal-organic nanotubes with aside of 2 nm. A uniform 1D channel is fabricated inside the tube, and H2O and alcohol can be selectively adsorbed. Its optical gap is about 0.76 eV of semiconductive region, and X-ray and theoretical studies revealed its unique electronic structure of CDW quartets. In addition, its electronic states can be successively controlled by exchanges of structural components and guest molecules. The results presented here demonstrate a rational route to the creation of nanotubes with high tunabilities of structures and electronic states, and might also offer valuable insights into multifunctional nanomaterials.
