(1) Department of Chemistry, University of North Texas, Denton, Texas, United States (2) University of Perugia, Perugia, Italy (3) Chemistry Division, School of Science and Technology, Camerino, Italy (4) University of North Texas, Denton, Texas, United States A series of new charge transfer compounds [M(3,5-(CF3)2pz)]3@D (where M = Cu, Ag, or Au; D = DBTTF, TTF, or BEDT-TTF) and [Ag(3,5-(NO2)2pz)]3@D (where D = DBTTF or TTF) have been synthesized and characterized by elemental analysis, IR, ESI-MS, 1H NMR, and single crystal X-ray diffraction analyses. This series of compounds have been found to exhibit remarkable supramolecular structures in both the solid state and solution, whereby they exhibit supramolecular stacked chains and oligomers, respectively. The supramolecular donor-acceptor solid and solution adducts also exhibit indefinite stability, even in the presence of air, and remarkable magento-opto-electronic properties, as highlighted by 1H and 19F NMR, UV/visible spectroscopy, magnetic susceptibility, and FT-IR investigations. The potential applications of this new class of supramolecular binary donor-acceptor adducts in molecular electronics, including solar cells, (super)conductors, magnetic switching devices, and field effect transistors (FETs) will be overviewed
