逐步说明:簇[3,3'-Co(1,2-C 2 B 9 H 11)2 ] -是通过脱氢碘化制备逐步可调的氧化还原电势系统的绝佳平台。在添加多达八个碘取代基(紫色;参见图片)时,E 1/2(Co III / Co II)值从-1.80 V下降至-0.68 V(vs。Fc + / Fc; Fc =二茂铁)。在聚吡咯的生长中已经观察到这种可调性的实际应用。
The metallacarborane [3,3′‐Co(1,2‐closo‐C2B9H11)2]− has been synthesized. This species allows the formation of redoxcouples in which both partners are negativelycharged. The E1/2 potential can be tuned by adjusting the nature and number of substituents on B and C. The octaiodinated species [3,3′‐Co(1,2‐closo‐C2B9H7I4)2]− is the most favorable, as it is isolatable and stable in air. A DFT study on
合成了金属碳硼烷[3,3'-Co(1,2- closo -C 2 B 9 H 11)2 ] -。该物种允许形成氧化还原对,其中两个伙伴都带负电。对E 1/2电位可通过调整上B和C的取代基的性质和数量被调节octaiodinated物种[3,3'-钴(1,2-闭合碳-C 2乙9 ħ 7我4)2 ] −是最有利的,因为它可隔离并在空气中稳定。DFT研究了复合物的稳定性和氧化还原电位。
