─ 1. Conducting molecular materials :
Synthesis of molecular materials precursors: electroactive ⺎-conjugated organic and or-ganometallic molecules (several examples of donor and acceptors: TTF; bis(dithiolene) complexes of Ni, Pd, Pt, Au; TCNQ. Functionalization/introduction of non-covalent inte-ractions: hydrogen, halogen, chalcogen. Intermolecular interactions in the solid – Open shell molecules: - neutral radicals, stabilization, delocalization – two-stage redox sys-tems (Würster, Weitz) – overlap interactions in the solid – mixed valence dimers – 1D materials – band structures – Peierls transition.
