Coordination Polymers for Nanoelectronics

Abstract

We review recent progress in the potential use of coordination polymers as molecular wires for nanoelectronics. To this end we review some basic aspects of these materials including synthesis and properties in the bulk scale; processability towards the formation of nanoscale structures and seminal works on electrical transport of coordination polymers. Finally, we summarize some of the perspectives in this field.

Electrical Behaviour of Heterobimetallic [MM′(EtCS2)4] (MM′=NiPd, NiPt, PdPt) and MM′X‐Chain Polymers [PtM(EtCS2)4I] (M=Ni, Pd)

“…It is highly dispersive in energy, thereby giving a very low effective hole mass (i.e., very good conduction properties). This result confirms that this class of coordination polymer is very promising for use in nanoscale electronic devices 16a. Notably, the parent [Pt 2 (RCS 2 ) 4 I] n MMX polymers, which were recently investigated by using the same DFT approach,10d, 21 exhibit metallic behaviour.…”

“…On-demand technological applications require the development of molecular wires with versatile electrical behaviour across long distances. [15,16] Furthermore, the possibility of modulating the intrinsic electronic nature of selected bimetallic subunits may be exploited in the formation of molecular wires with controlled electrical properties. One way to pursue these goals involves tuning the electronic properties of the bimetallic entity.…”

Reversible Solvent‐Exchange‐Driven Transformations in Multifunctional Coordination Polymers Based on Copper‐Containing Organosulfur Ligands

“…This change implies a slight change of the interplanar distances from 6.146 Å for compound 4 to 6.173 Å for 6 . A similar trend between the solvent molecules and the interplanar distance is observed in an analogous family containing chloride anions 11,12…”

The Isolation of Single MMX Chains from Solution: Unravelling the Assembly–Disassembly Process

“…[12] MMX chains are therefore promising candidates for nanoelectronic applications in which molecular wires that can transport electrical charges across long distances are required. [10,13] Furthermore, the relatively low work function (ca. 3.7 eV) [14] and the fact that thin films of MMX are almost transparent for thicknesses lower than 50 nm make this class of structure extremely appealing for molecular electronics and optoelectronics.…”
