“…The choice of method depends, amongst other things, on the availability of the starting materials. Usually, as in the case of the preparation of TTFs [9,12,16], 1,3-dithiole-2-ketones have been used as starting materials [12,16,70,[73][74][75]97,113] and the required neutral M 1,2-DTs were obtained from them, according to a three-step procedure of Scheme 1.…”

Neutral Metal 1,2-Dithiolenes: Preparations, Properties and Possible Applications of Unsymmetrical in Comparison to the Symmetrical

This paper is an overview concerning the preparations and properties as well as possible applications of neutral (one component) metal 1,2-dithiolenes (and selenium analogues). The structural, chemical, electrochemical, optical and electrical behavior of these complexes depend strongly on the nature of ligand and/or the metal. The results of unsymmetrical in comparison to those of symmetrical complexes related to the properties of materials in the solid state are primarily discussed. The optical absorption spectra exhibit strong bands in the near IR spectral region ca. 700 to ca. 1950 nm. X-ray crystal structure solutions show that the complexes usually have square-planar geometry with S-S and/or M-S contacts. Some of them behave as semiconductors or conductors (metals) and are stable in air. The cyclic voltammograms at negative potentials are different from the corresponding potentials of tetrathiafulvalenes (TTFs). As a consequence, the LUMO bands occur at much lower levels than those of TTFs. Consequently, electrical measurements under conditions of field effect transistors exhibit n-type or ambipolar behavior. Illumination of materials with high power lasers exhibits non-linear optical behavior. These properties enable metal 1,2-dithiolene complexes to be classified as promising candidates for optical and electronic applications, (e.g., saturable absorbers, ambipolar inverters).

“…For example, in [Ni(Pr 2 timdt)(dmit)], the C-S and C-C distances for the ligand Pr 2 timdt are 1.69 and 1.38 Å, while for the ligand dmit the distances are 1. 74 [63] with permission of the Verlag der Zeitschrift für Naturforschung, and photograph of crystal [77].…”

“…However, this effect is clear with compounds 1 (R = CH 3 ), 11 and 23, the latter possessing the mixed structure of the other two. Its oxidation and reduction potentials are in the intermediate of those of the corresponding compounds.Electrochemical studies of type 18 complexes bearing linear or branched long chain alkyl groups (R = n-heptyl and 2-ethylhexyl), have been recently reported and show the possibility of reaching electrochemical gaps in the solid state[102]. The measured bandgaps are in the range of 0.6-0.9 eV and are sensitive to the electrochemical medium.…”

International audienceThe cavity microelectrodes (CMEs) have been introduced in the 1990s and since then have been employed for the characterization of various types of materials ranging from materials used for energy storage, biological applications, catalysis characterization, or corrosion studies. This technique takes advantage of working on small amount of pure electroactive materials (few hundreds nanograms) using usual electrochemical techniques (cyclic voltammetry, electrochemical impedance spectroscopy, etc.) and allows a rapid screening of the electrochemical behavior of new materials. The CME development and its main applications for the electrochemistry of powder materials are reviewed and discussed
