Six Unimolecular Rectifiers and What Lies Ahead

  • Chapter

Part of the book series: Lecture Notes in Physics ((LNP,volume 680))

Abstract

Six unimolecular rectifiers are discussed: γ-hexadecylquinolinium tricyanoquinodimethanide, 1, and two thioacetyl derivatives of 1, namely (Z)- α-cyano-β-[N-tetradecylthioacetylquinolin-4-ylium)-4-styryl-dicyanomethanide, 2, and (Z)-α-cyano-β-[N-hexadecylthioacetylquinolin-4-ylium)-4-styryl-dicyanomethanide, 3, and three other rectifiers of very different structure: 2,6-di[dibutylaminophenylvinyl]- 1-butylpyridinium iodide, 4, dimethylanilino-aza[C60]-fullerene, 5, and fullerene-bis-[4-diphenylamino-4”-(N-ethyl-N-2” ’-ethyl)amino-1,4-diphenyl-1,3-butadiene] malonate, 6. Monolayers of these molecules exhibit asymmetric electrical conductivity between Au or Al electrodes. We also suggest approaches towards one-molecule electronic devices, useful for the ultimate reduction in circuit sizes.
