We present the synthesis and oxoanion-assembling properties of a monomer with a naphthalene ring as a central core decorated with two arms containing iodotriazolium rings as anion binding sites. Interactions with SO, HPO, and HPO anions, via a cooperative mechanism, afforded new supramolecular materials stabilized by a combination of halogen- and hydrogen-bonding interactions. H NMR experiments and solid-state structure provided evidence for the initial formation of a supramolecular linear chain, nucleation step, and then two different supramolecular chains are interpenetrated with each other, elongation steps, involving the formation of hydrogen bonds between two oxygens of the anion from one of the chains and the naphthalene inner protons from the other chain. Scanning electron microscopy studies revealed that the morphology of the crystals changed dramatically with the nature of the anion added.
我们提出了一种单体的合成和氧阴离子组装性质，该单体以萘环为中心核心，两个臂上装饰有碘三唑环作为阴离子结合位点。通过协同机制与 SO、HPO 和 HPO 阴离子相互作用，提供了新的超分子材料，由卤键和氢键相互作用的组合稳定。H NMR 实验和固态结构提供了初步形成超分子线性链、成核步骤的证据，然后两条不同的超分子链相互贯穿，涉及到一条链上的阴离子的两个氧原子与另一条链上的萘内质子之间形成氢键，从而实现伸长步骤。扫描电子显微镜研究表明，晶体的形态随着加入的阴离子的性质而发生显著变化。
