important parameters of adsorbents, and mesoporous materials have received intense attention for large guests. Here, a series of mesoporous coordination polymers underlying a new framework prototype for fast expansion of pore size is reported and the profound effect of pore size on adsorption heat transformation is demonstrated. Three isostructural honeycomb‐like frameworks are designed and synthesized by
孔径是吸附剂最重要的参数之一,介孔材料已受到大客的关注。在此,报道了一系列介孔配位聚合物,这些介孔聚合物是新构架原型的基础,该构架原型可实现孔径的快速扩展,并证明了孔径对吸附热转化的深远影响。通过将对位线性草酸金属链和三角形三吡啶配体相结合,设计和合成了三个等结构的蜂窝状骨架。将配体桥接长度从5.5更改为8.6和9.9Å,有效孔径从20变为33和37Å,表面积从2096到2630和2749 m 2 g -1,孔体积从1.19到1.93和2.36 cm 3克-1, 分别。凭借中孔独特且可调节的等温线形状,使用R-134a(1,1,1,2-四氟乙烷)可实现高达1.19 gg -1或0.38 g cm -3的超大工作容量,用于吸附热转化作为工作流体。

for directing the synthesis of the 6-porphyrin nanoring, in keeping with their negative cooperativity of binding. In contrast, the binding of a 12-porphyrin nanoring to two hexadentate ligands occurs with high positive allosteric cooperativity (α > 40), and the ligand is an effective Vernier template for directing the synthesis of the 12-porphyrin nanoring. This stacked Vernier template approach creates
