About this collection
The concept of molecular electronics was inspired by the desire to harness the electrical properties of one or more molecules trapped between macroscopic electrodes under bias to perform functions analogous to those solid-state electronic components at an ultra-miniaturized scale. Progress in the field ebbed and flowed from the 1950s to 2000s as concepts, theories and experiments met with frustrations arising from the technical challenges of achieving these goals. With the advent of laboratory methods for the construction of electrode-molecule-electrode junctions, molecular electronics has emerged as a genuine field of endeavor, with ambitions and applications that far exceed the initial premise. This Spotlight Collection on Inorganic Molecular Electronics aims to highlight recent developments in the application of the structural, optical, electronic and magnetic properties of inorganic complexes and organometallic complexes in molecular electronics, and the theories, synthetic, analytical, and physical approaches that deliver unique molecular systems with customized and controlled properties.
Current research with metal complexes in junctions emphasizes new concepts and strategies for electron transport in junctions, the design of logic devices, and the development of molecular components such as wires, memory elements, transistors, memristors, rectifiers, or on/off switches. Beyond electronics, molecular junctions attract interest as tools for the development of spintronics, single-molecule sensing systems, thermoelectrics, and an increasingly wide array of materials science applications.
This collection is guest edited by Dalton Transactions Advisory Board member Prof. Cláudio Verani (Wayne State University, USA), and Prof. Paul Low (University of Western Australia, Australia).
