Abstract

The disclosed subject matter relates compounds of structure (I), and polymers of structure (II) having a polydispersity ranging from 1 to about 1.1, compositions comprising said polymers and a spin casting solvent, the process of forming a pinning layer selectively on metal with said composition and the process of using said pinning layers to affect chemoepitaxy directed self-assembly of an overlying block copolymer, and the subsequent process of pattern transfer of this self-assembled layer into a substrate by etching.
