Reactions of ZrCl(4) and single or mixed linear dicarboxylic acids bearing methyl or azide groups lead to highly stable isoreticular metal-organic frameworks (MOFs) with content-tunable, accessible, reactive azide groups inside the large pores. These Zr-based MOFs offer an ideal platform for pore surface engineering by anchoring various functional groups with controlled loadings onto the pore walls via the click reaction, endowing the MOFs with tailor-made interfaces. Significantly, the framework and crystallinity of the functionalized MOFs are well-retained, and the engineered pore surfaces have been demonstrated to be readily accessible, thus providing more opportunities for powerful and broad applications of MOFs.
ZrCl(4)与单或混合的带有甲基或叠氮基团的线性二羧酸反应，生成具有可调节含量、可及性和反应性叠氮基团的高度稳定的同构金属-有机骨架（MOFs），这些基团位于大孔内。这些基于 Zr 的 MOFs 提供了一个理想的平台，通过点击反应将各种功能基团以受控的负载量锚定在孔壁上，对孔表面进行工程化，赋予 MOFs 定制的界面。重要的是，功能化 MOFs 的骨架和结晶度得以很好地保留，并且已经证明可以很容易地进入工程化的孔表面，从而为 MOFs 的强大和广泛应用提供了更多机会。
