Molecule and Electron Transfer through Coordination-Based Molecular Assemblies

Abstract

This study provides insight into the internal structure of surface-confined molecular assemblies. The permeability of the layer-by-layer grown thin films can be controlled systematically by varying their composition and the structure of their molecular components. Moreover, the thickness can be used to control molecule permeation versus electron transfer.

Surface‐Confined Heterometallic Molecular Dyads: Merging the Optical and Electronic Properties of Fe, Ru, and Os Terpyridyl Complexes

“…Note also that the redox potentials for the individual molecular dyads depend on electron donating or withdrawing effect of one substituent on other. The strong peaks observed for both components of the dyads indicate that the film structure is porous enough to allow the penetration of electrolytes to the underlying ITO substrate 22. Moreover, the system exhibited excellent redox reversibility (see Figure S7b, Supporting Information) and displayed minimum degradation (<10%) after 10 3 oxidation/reduction cycles.…”

Molecular Sieving and Current Rectification Properties of Thin Organic Films

“…Electrochemical devices with current rectification properties have been originally reported by Murray et al 20 Briefly, electrochemical current rectifiers (ECR) consist in surfaces functionalized by redox species allowing unidirectional current of solution-phase redox probe to pass through. ECR could be realized using surfaces functionalized through a wide range of techniques including Self-Assembled Monolayers (SAMs), 21 coordination-based molecular assemblies 22 or biological interfaces 23 to quote a few.…”

Facile Construction of Structurally Defined Porous Membranes from Supramolecular Hexakistriphenylamine Metallacycles through Electropolymerization

“…For example, we have successfully created large‐scale ordered honeycomb structures from platinum‐acetylide organometallic gels . Moreover, some layer‐by‐layer‐grown apertured films were reported to feature highly efficient molecule permeation properties ,. However, it is still very challenging to realize well‐controlled pore structures.…”
