A series of dialdehyde compounds were synthesized and reacted with the complementary triamines (either planar or pyramidal with a 109.5° vertex) in a 3:2 ratio to explore the structural requirements on the building blocks for the successful construction of shape-persistent, covalent organic polyhedrons (COPs). Structural variations in the building blocks included the distance and angle between the
合成了一系列二醛化合物,并以3:2的比例与互补的三胺(平面或金字塔形的顶角为109.5°的三胺)反应,以探索成功构建形状持久的共价有机物的结构要求。多面体(COP)。结构单元中的结构变化包括两个反应位点(醛或胺官能团)之间的距离和角度以及是否存在增溶链。利用计算机建模来确定和比较其中一些COP结构的热力学稳定性。此外,进行了气体吸附研究,以探索这些分子笼在气体分离(尤其是碳捕获)应用中的潜力。
