Abstract
The present invention relates to novel cross-linkable polymers and a wide variety of electronic devices containing at least one layer having the polymer. The compounds can function as monomers, and copolymers can be formed from such monomers, such copolymers comprising, as polymerized units, a plurality of units of the compounds.
