In the present study, β-cyclodextrin-based nanosponges were prepared by reaction of β-cyclodextrin with dicarbonyl imidazole as a crosslinker agent. The synthesized polycarbonate nanosponge was characterized by FT-IR spectroscopy, thermogravimetric analysis, scanning electron microscopy and Brunauer–Emmett–Teller. The catalytic activity of β-cyclodextrin-based nanosponges was successfully tested in the one-pot three-component condensation of kojic acid, aromatic aldehydes and various aromatic amines. The superiority of this new strategy is short reaction times, high yields and utilizing of biodegradable and nontoxic nanocatalyst.

超交联的β-环糊精纳米海绵：一锅合成曲酸基杂环化合物的三维多孔可生物降解催化剂

在本研究中，通过β-环糊精与二羰基咪唑作为交联剂的反应制备了基于β-环糊精的纳米海绵。合成的聚碳酸酯纳米海绵通过FT-IR光谱，热重分析，扫描电子显微镜和Brunauer-Emmett-Teller进行了表征。β-环糊精基纳米海绵的催化活性已在曲酸，芳族醛和各种芳族胺的一锅三组分缩合反应中得到成功测试。这种新策略的优势在于反应时间短，产率高以及可生物降解且无毒的纳米催化剂的利用。
