Ferrocenes as Building Blocks in Molecular Rectifiers and Diodes

Abstract

Ferrocenes have recently been reported as components of a number of molecular circuits. This short review covers reports of ferrocenes in molecular rectifiers and diodes which have appeared in the last 10 years.

Forever young: the first seventy years of ferrocene

“…The more advanced applications are based on the tuneable electrochemical and optical properties of ferrocene, which make its derivatives attractive stimuli-responsive materials for optics (also nonlinear) and molecular electronics. 190 The research in this area is extremely diverse and, hence, difficult to summarise briefly. In addition, ferrocenes have been studied as liquid-crystalline materials, 191 additives for rechargeable batteries, 192 and photoinitiators for polymerization reactions.…”

Tailoring quantum transport efficiency in molecular junctions via doping of graphene electrodes

“…Asymmetric IV behavior in molecular junctions has been reported in numerous publications and typically requires two prerequisites: an asymmetric junction structure and an asymmetric electrostatic potential spatial profile. [48][49][50] SAMs 2 possess a relatively symmetric junction structure with pyridine groups at both ends of the molecular backbone, and the carbazolebased tetrapodal group of SAMs 2 molecule has been demonstrated to solely assist in SAM formation without participating in the electron transport process. 27 Although the electrodes differ, the work function of graphene and gold is generally comparable.…”

Ferrocenes as One-Electron Donors in Unimolecular Rectifiers

“…There has also been a recent brief review on this exact topic [43]; for the sake of brevity, we refer the reader to the papers cited for other significant rectifiers containing the donor ferrocene [43][44][45][46][47][48][49].…”
