Copper Salts of Rigid N,N′-Dicyanoquinone Diimine Derivatives

N,N‘-Dicyanoquinone Diimines (DCNQIs): Versatile Acceptors for Organic Conductors

“…The DCNQIs 97 − 112 (Table , entries 93−108) were designed for donor effects from the heterocyclic residues. − They are accompanied by other heterocyclic DCNQI type acceptors ( 113 − 130 , entries 109− 126). Compounds 120 − 122 (entries 116−118) carrying cationic substituents, i.e., the corresponding radicals, are zwitterions …”
