Abstract
The fundamental properties and applications of organic charge transfer complexes based on Pb(TCNQ)(2)(Pb = lead, TCNQ = 7,7,8,8-tetracyanoquinodimethane) and its fluorinated derivatives are relatively unknown. Here, a facile solid-liquid approach for the synthesis of Pb(TCNQ)(2)and Pb(TCNQF(4))(2)is reported. These materials are thoroughly analyzed to obtain insights into their unique morphological, vibrational and optical properties, the latter extending across the UV-Vis-IR region. Subsequently, the catalytic potential of these materials is evaluated by employing a model redox reaction, which revealed two orders of magnitude higher catalytic activity of the fluorinated derivative over non-fluorinated Pb(TCNQ)(2)crystals. Overall, the work presented here adds a new member to the growing yet limited library of metal-organic charge transfer complexes and validates the outstanding redox catalysis performance of this group of materials.
