Hierarchical super-architectures from small molecule self-assembly have interesting properties and play an indispensable role in many fields. In most cases, a self-assembly process refers to multiple intermolecular interactions among intricately designed building blocks. Here, a supramolecular assembly with a tubular morphology with dimensions ranging from nanometers to micrometers was prepared through self-assembly of 3,5-dimethyl-4-iodopyrazole (DMIP), a molecule with an unprecedented simple structure. As predicted by density functional theory (DFT) calculations, the hydrogen bond and halogen bond interaction energy between DMIP molecules can be up to 32.81 kJ mol−1, which effectively drives DMIP molecules to assemble into fibrils, sheets, and finally, tubular architectures. Intriguingly, the formed tubular structure can be easily removed by heating at 100 °C, enabling the material to function as a disposable template to guide linear organization of nanostructures. As a proof of concept, ordered Au or Ag nanochains with diameters ranging from 18 to 120 nm were facilely prepared in high yield.

3,5-二甲基-4-碘吡唑的超分子纳米管/微管的自组装，用于等离子纳米粒子的组织†
小分子自组装的分层超体系结构具有有趣的特性，并在许多领域中起着不可或缺的作用。在大多数情况下，自组装过程是指复杂设计的构建基块之间的多种分子间相互作用。在这里，通过3,5-二甲基-4-碘吡唑（DMIP）的自组装，制备了具有从纳米级到微米级的管状形态的超分子组装体，该分子具有前所未有的简单结构。如密度泛函理论（DFT）计算所预测，DMIP分子之间的氢键和卤素键相互作用能最高可达32.81 kJ mol -1，可以有效地驱动DMIP分子组装成原纤维，薄片和最终的管状结构。有趣的是，可以通过在100°C下加热轻松去除形成的管状结构，从而使该材料可用作一次性模板来引导纳米结构的线性组织。作为概念的证明，可以容易地以高产率制备直径为18至120 nm的有序Au或Ag纳米链。
