Synthesis and characterization of end-functionalized carbosiloxane dendrimers

Dendritic carbosilanes containing 48 and 96 functional groups on the periphery were prepared. The reaction of the fourth and fifth parent dendritic generations (G4‐48Cl and G5‐96Cl) with alcohol [9‐anthracene methanol, 8‐hydroxyquinoline, 4‐hydroxyazobenzene, 2‐hydroxymethylanthraquinone, and 5‐(2‐h...

Description
Summary:Dendritic carbosilanes containing 48 and 96 functional groups on the periphery were prepared. The reaction of the fourth and fifth parent dendritic generations (G4‐48Cl and G5‐96Cl) with alcohol [9‐anthracene methanol, 8‐hydroxyquinoline, 4‐hydroxyazobenzene, 2‐hydroxymethylanthraquinone, and 5‐(2‐hydroxyethyl)‐4‐methylthiazole] 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. © 2001 John Wiley & Sons, Inc.
