Electrospun PUiO-66 exhibits a nanostructure with nanofiber diameters in the 150–400-nm range.

In addition to B and N elements, which have catalytic roles, the immobilization of Zr(IV) and Ni(II) on the BN-CNS surfaces created the special bifunctional acid–base catalyst. The prepared catalyst was identified by various characterization techniques, and the efficiency of the catalyst for the synthesis of benzo[<i>g</i>]pyrimido[4,5-<i>b</i>]quinolinetetraon derivatives was explored in water media at 80°C. High to excellent yield of products, easy recovery of the catalyst, and green reaction conditions are some of the merits of the presented method.</p>\u0000 </div>","PeriodicalId":8344,"journal":{"name":"Applied Organometallic Chemistry","volume":"39 10","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144927175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
