  Pyridyl dicyanoquinodimethane acceptors for electroactive solids

  摘要：

  A new synthetic strategy for dicyanoquinodimethane electron acceptors is presented and used to synthesize six such compounds for the first time. The general sequence is substitution of alpha,alpha'-dicyanoxylene alpha anions with electrophiles followed by oxidative dehydrogenation. Unlike most previous examples, these quinodimethanes (QDs) are alpha substituted, rather than ring substituted; thus, the substituents increase the aspect ratio of the QDs and extend the pi-systems. All contain at least one pyridyl substituent at an alpha-position, and the set includes polar, cationic, and phosphonic acid derivatives. The particular compounds were chosen for incorporation into specific types of potentially electroactive solids, although, in principle, the syntheses could accommodate a wide variety of other functional groups. The neutral QD compounds display two reversible reductions, while the cations show single, partially reversible electrochemical transitions. Syn-anti isomerism was noted for several of the QDs, and proton NMR assignments obtained by 2D COSY methods are reported.
