Dendritic carbosilanes containing 48 and 96 functional groups on the periphery were prepared. The reaction of the fourth and fifth parent dendritic generations (G4-48CI and G5-96CI) with alcohol [9-anthracene methanol, 8-hydroxyquinoline, 4-hydroxyazobenzene, 2-hydroxymethylanthraquinone, and 5-(2-hydroxyethyl)-4-methyl-thiazole] in the presence of 1,1,2,2-tetramethylethyenediamine produced end-functionalized dendrimers with very high yields. The polydispersity indices of the prepared dendrimers revealed unchanged narrow values between the fourth and fifth generations.
