Abstract

The synthesis of polystyrene-b-poly(methyl methacrylate) diblock copolymers with a luminescent ruthenium(II) tris(bipyridine) [Ru(bpy)₃] complex at the block junction is described. The macroligand precursor, polystyrene bipyridine-poly(methyl methacrylate) [bpy(PS–H)(PMMA)], was synthesized via the atom transfer radical polymerization of styrene and methyl methacrylate from two independent, sequentially activated initiating sites. Both polymerization steps resulted in the growth of blocks with sizes consistent with monomer loading and narrow molecular weight distributions (i.e., polydispersity index < 1.3). Subsequent reactions with ruthenium(II) bis(bipyridine) dichloride [Ru(bpy)₂Cl₂] in the presence of Ag⁺ generated the ruthenium tris(bipyridine)-centered diblock, which is of interest for the imaging of block copolymer microstructures and for incorporation into new photonic materials. © 2002 Wiley Periodicals, Inc.

31 The ligands are abbreviated in the following manner: 4-R¹–4′-R²–2,2′-bipyridine = bpy(R¹)(R²). For block copolymeric ligands, R¹ corresponds to the first block grown, and R² refers to the second. For example, a bpy-centered diblock in which PS was grown before a PMMA chain was grown would be represented as bpy(PS–H)(PMMA).
