Organic rectifying junctions fabricated by ionic coupling.
Ionically-assembled structures that comprise discrete layers of cationic acceptors (4,4'-bipyridinium) and anionic donors (copper phthalocyanine-3,4',4'',4'''-tetrasulfonate) exhibit asymmetric current-voltage (I-V) characteristics with high rectification ratios of 60-100 at +/-1 V.
