A straightforward method for the synthesis of a two-dimensional (2D) new copper(I) coordination polymer, namely Cu(bzpdc), containing the ligand benzophenone 4,4′-dicarboxylate, and its effective use as catalyst for the azide–alkyne click chemistry at room temperature is reported. Zig-zag formation caused by cuprophilic interactions resulted in an unprecedented crystal structure with a very high copper content (45.5% by weight). The catalyst was stable up until 300 °C and tolerant to various solvents, including water. Cu(bzpdc) showed excellent catalytic activity for click reactions of several organic azides and alkynes having different functional groups at room temperature and is comparable to its homogenous analogues. The recyclability of Cu(bzpdc) was also tested and proven to be effective.

一种不寻常的之字形二维铜 (I) 配位聚合物作为室温下叠氮化物-炔烃“点击”化学的出色催化剂

一种直接合成二维 (2D) 新铜 ( I ) 配位聚合物的方法，即 Cu(bzpdc)，包含配体二苯甲酮 4,4'-二羧酸酯，及其作为叠氮-炔烃催化剂的有效用途报告了室温下的点击化学。由亲铜相互作用引起的之字形形成导致前所未有的晶体结构，具有非常高的铜含量（45.5% 重量）。该催化剂在 300 °C 之前都是稳定的，并且对包括水在内的各种溶剂具有耐受性。Cu(bzpdc) 在室温下对几种具有不同官能团的有机叠氮化物和炔烃的点击反应显示出优异的催化活性，并且与其均相类似物相当。还测试了 Cu(bzpdc) 的可回收性并证明是有效的。
