The Editorial Board found that substantial portions of the text came from other published papers. The scientific community takes a very strong view on this matter, and the International Journal of Organic Chemistry treats all unethical behavior such as plagiarism seriously.

A n-Hexyl NH 3Sr 2Nb 3O 10 is obtained by the stepwise ion-exchange reaction,then is dispersed in aqueous solution of trinuclear acetato-hydroxo iron(III) nitrate,[Fe 3(OCOCH 3) 7OH·2H 2O]NO 3,and the ...A n-Hexyl NH 3Sr 2Nb 3O 10 is obtained by the stepwise ion-exchange reaction,then is dispersed in aqueous solution of trinuclear acetato-hydroxo iron(III) nitrate,[Fe 3(OCOCH 3) 7OH·2H 2O]NO 3,and the interlayer potassium cations of the perovskite niobate are exchanged with the partially hydrolyzed trinuclear acetato complex ions.On heating,the exchanged complex ions are converted into iron oxide pillars which keep the perovskite sheets apart.The product is characterized by XRD,SEM,EDAX and surface area measurement respectively.展开更多
为了扩大柱[5]芳烃衍生类型,扩展其在主客体化学与分子器件等领域的潜在应用,以1,4-二甲氧基柱[3]芳烃[2]醌(或1,4-二甲氧基柱[4]芳烃[1]醌)为原料,1,8-二氮杂二环十一碳-7-烯和过氧化叔丁醇为催化剂,制备环氧化醌类柱[5]芳烃,并采用1 H...为了扩大柱[5]芳烃衍生类型,扩展其在主客体化学与分子器件等领域的潜在应用,以1,4-二甲氧基柱[3]芳烃[2]醌(或1,4-二甲氧基柱[4]芳烃[1]醌)为原料,1,8-二氮杂二环十一碳-7-烯和过氧化叔丁醇为催化剂,制备环氧化醌类柱[5]芳烃,并采用1 H NMR、13 C NMR、高分辨质谱和X-射线衍射测试其结构性质。结果表明:合成反应条件温和,收率较高,收率分别为81%和42%;1 H NMR实验和X-射线衍射法表明,与1,4-二甲氧基柱[4]芳烃[1]醌相比,环氧化柱[4]芳烃[1]醌结构中一个对苯二甲醚单元空间位置发生约为90°偏转;而1 H NMR数据和结构模拟图表明,环氧化柱[3]芳烃[2]醌中对苯二甲醚单元并未有偏转,成规整的柱型空腔。柱[5]芳烃衍生物及其结构信息为进一步构筑柱[5]芳烃高级组装体奠定基础。展开更多
