Synthesis of efficient and reusable catalyst was carried out by immobilization of azacrown ether onto the covalently linked amine-functionalized mesoporous MCM-41 via a simple method. Application of this linked azacrown ether functionalized MCM-41 catalyst was also investigated as an effective, heterogeneous and host material in the regioselective ring opening and triazole cyclization of epoxides by phenylacetylene and sodiumazide in click reaction. The heterogeneous catalyst was characterized by TGA,XRD,TEM, ¹HNMR, ¹³CNMR and FT-IR techniques. The results of theses analysis showed that, MCM-41@azacrown-Cu with a 22.99% mol loading of copper has given excellent catalytic activity and high efficiency in short time. It is noted that one of the most valuable factors in this work is the recyclability of the catalyst.

通过简单的方法，将氮杂冠醚固定在共价连接的胺官能化的介孔MCM-41上，从而进行了有效且可重复使用的催化剂的合成。还研究了这种连接的氮杂冠醚功能化的MCM-41催化剂在点击反应中通过苯乙炔和叠氮化钠在环氧化物的区域选择性开环和三唑环化中作为一种有效的，非均相的和主体材料的应用。该非均相催化剂的特征在于TGA，XRD，TEM，¹ HNMR，¹³CNMR和FT-IR技术。这些分析结果表明，具有22.99％摩尔铜负载的MCM-41 @ azacrown-Cu在短时间内具有优异的催化活性和高效率。应当指出，这项工作中最有价值的因素之一是催化剂的可回收性。
