| Résumé : |
Dithiolene complexe, built from two thiolate bridged by a conjugated ethylneic or aromatic moiety are known to exhibit a variety of oxidation states. Their peculiar electronic structure, with a small HOMO-LUMO gap, allows strong optical transitions to be observed in the NIR with a possible aplication as lasser dyes. Besides, the strong delocalization of the spin density on the dithiolene ligands in the paramagnetic complexes leads to molecular solids with cooperative electronic propertie (antiferromagnetism, metallic conductivity or superconductivity) or low-dimensional magnetism (spin chains, spin ladders). |
