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(TCNQF4)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.

Pb(TCNQ)2和Pb(TCNQF4)2的金属-有机电荷转移配合物作为电子转移反应的新催化剂

基于Pb(TCNQ)2(Pb =铅,TCNQ = 7,7,8,8-四氰基喹二甲烷)及其氟化衍生物的有机电荷转移配合物的基本性质和应用尚不清楚。在这里,报道了一种简便的固液合成Pb(TCNQ)2和Pb(TCNQF 42的方法。对这些材料进行了全面分析,以深入了解其独特的形态,振动和光学特性,后者延伸至UV-Vis-IR区域。随后,通过使用模型氧化还原反应评估了这些材料的催化潜力,该反应表明氟化衍生物相对于非氟化Pb(TCNQ)2的催化活性高两个数量级。晶体。总体而言,此处介绍的工作为不断增长但数量有限的金属-有机电荷转移配合物库增加了新成员,并验证了这类材料出色的氧化还原催化性能。
