Patent ID: 8057908

Claim:
A device comprising a substrate; and a hole transport composition comprising a polymeric hole transport component and a product selected from: (a) a sorption product of said substrate and a silylated aryl amine component, (b) an intermolecular cross-linking product of two silylated aryl amine components, and (c) combinations of a said sorption product and a said intermolecular cross-linking product; wherein said silylated aryl amine component is of a formula selected from where Ar is arylene; n is an integer ranging from 1 to 4; R 1 -R 7 are independently selected from H and alkyl moieties ranging from C 1 to C 6 , each said alkyl moiety comprising a hydrolyzable silyl group, and wherein at least one of R 1 -R 3 and at least one of R 4 -R 7 is one of said alkyl moieties, and wherein each silyl group of each said product comprises three silicon-oxygen bonds.
