Organic–inorganic hybrid 4f-π conductors

Combining 4f-element complexes with highly conductive molecules like TMTSF (tetramethyltetraselenafulvalene) and TCNQ (tetracyanoquinodimethane) enables the preparation of multifunctional organic–inorganic hybrid materials that could demonstrate both electronic conduction and magnetic properties. These materials hold great promise for applications in molecular electronic devices and related fields. However, creating such materials poses a significant challenge due to the need to integrate both conductive and magnetic ions into the assembly networks. This review article presents the origin, development, and recent advancements in this research field. We believe that these organic–inorganic hybrid materials could behave as an intriguing platform for exploring novel types of multifunctional molecular materials and for delving into the fundamental understanding of 4f-π interactions.
