strategy towards novel 1,2,4-triazole dendrimers, in which 3,5-dichloro-4-(4-methoxyphenyl)-4H-1,2,4-triazole was used as the heterocyclic building block, was successfully explored. Nucleophilic aromatic substitution at this novel AB2-monomer was used as the key step in the propagation of the heterocyclic dendrons and these dendrons were attached to both a 1,3,5-triazine and a methylene core. The peripheral
一种趋向于合成新型1,2,4-三唑树枝状大分子的合成策略,其中使用3,5-二氯-4-(4-甲氧基苯基)-4 H -1,2,4-三唑作为杂环结构单元成功探索。在这种新颖的AB 2-单体处的亲核芳香取代被用作杂环树枝状分子繁殖的关键步骤,并且这些树枝状分子同时附着在1,3,5-三嗪和亚甲基核上。外围的1,2,4-三唑不仅可以通过亲核芳族取代而且可以通过铃木交叉偶联来改变。提出的树枝状聚合物是有前途的候选物,可用于可利用大量杂原子或需要对所施加条件有更好抵抗力的应用中。
