Synthesis of metal–organic materials is often dependent on the reaction conditions of suitable solvent/solvent mixture and temperature. A new finding based on a previously described protocol is reported: instead of obtaining metal–organic polyhedra (MOP), a metal–organic framework (MOF) with a 2D layered structure is obtained, following the same reported protocol. The 2D Cu(II)–5‐prop‐2‐ynoxyisophthlate MOF, crystallized in a kagomé‐type structure, is synthesized using different solvent systems at room temperature, as well as under solvothermal (nonhydrothermal) conditions. Under harsh reaction conditions, alkyne functional groups maintain their integrity and the copper does not catalyze the oxidative coupling of the terminal alkyne groups. X‐ray diffraction analyses confirm the structure and phase purity of the product. Based on the present results and the previous work reported by Zhao et al., it seems that two products, namely 0D MOP and 2D MOF, are equally possible when using the same reactants under same reaction conditions. However, the materials obtained in all the trials are MOF instead of MOP. From the structure point of view, there is a difference in connectivity of the initial building units that determines whether the product is MOP or MOF.

直接合成5D-Prop-2-丙氧基-2-邻苯二甲酸铜（II）MOF：评论“通过点击化学对多孔配位纳米笼进行表面官能化及其在药物递送中的应用”

金属有机材料的合成通常取决于合适的溶剂/溶剂混合物的反应条件和温度。据报道，基于先前描述的协议的新发现：代替获得金属有机多面体（MOP），遵循相同的报告协议，获得了具有二维分层结构的金属有机框架（MOF）。在室温下以及在溶剂热（非水热）条件下，使用不同的溶剂系统合成了以kagomé型结构结晶的二维Cu（II）-5-prop-2-丙氧基异磺酸盐MOF。在苛刻的反应条件下，炔烃官能团保持其完整性，铜不催化末端炔烃基团的氧化偶联。X射线衍射分析证实了产品的结构和相纯度。根据目前的结果和Zhao等人先前的研究，当在相同的反应条件下使用相同的反应物时，两种产品，即0D MOP和2D MOF似乎是同等可能的。但是，在所有试验中获得的材料都是MOF而不是MOP。从结构的角度来看，确定产品是MOP还是MOF的初始建筑单元的连通性有所不同。
