First Claim
Patent Images
1. A method for attaching a conductive oligomer to a gold electrode comprising:
- (a) providing a conductive olizomer with at least a first subunit comprising a sulfur atom protected by a protective group selected from the group consisting of ethyl pyridine or trimethylsilylethyl; and
(b) attaching said sulfur atom to said gold electrode.
