| Popis: | The synthesis of new tetrasubstituted pyridyl-containing cyclopentadienone, namely, 3,4-bis(4-(phenylethynyl)phenyl)-2,5-di(pyridin-2-yl)cyclopenta-2,4-dien-1-one is reported for the first time as a monomer for dendrimer synthesis. The synthesis by Diels—Alder approach allowed to prepare 2nd generation dendrimer with phenylethynyl peripherial fragments. A presence of triple bonds in the structure of dendrimers determines the possibility of their subsequent modification, in particular, by coordinating with metal compounds to obtain catalytically active nanocomposites. |
