In this work, we present the formation of two open-ended hexagonal-prism tubular macrocycles by the [6 + 12] self-assembly of the symmetric ∼120° organic ligand donor with ∼90° Pt(II) acceptor in a 1:2 ratio. The assembled structures were characterized by multinuclear NMR (H NMR, P{H} NMR, and H-H COSY NMR), electrospray ionization mass spectrometry (ESI-TOF-MS), traveling wave ion mobility-mass spectrometry (TWIM-MS), and transmission electron microscopy. Molecular modeling was further conducted to get insight into their structured characteristics. We also examined their photophysical properties.
在这项工作中，我们展示了通过在 1:2 比例下，对称的约 120°有机配体供体与约 90°的 Pt(II)受体的[6+12]自组装，形成了两个开口的六棱柱管状大环。组装结构通过多核 NMR（H NMR、P{H} NMR 和 H-H COSY NMR）、电喷雾电离质谱（ESI-TOF-MS）、行波离子淌度-质谱（TWIM-MS）和透射电子显微镜进行了表征。进一步进行了分子建模以深入了解它们的结构特征。我们还研究了它们的光物理性质。
