Novel*-extended thiophene-fused TCNQ-type and DCNQI-type acceptors have been synthesized from the corresponding quinones by reaction with Lehnert's reagent anbbis (trimethylsily1) carbodjimide (BTC), respectively. Additionally, an example of the little-known hybrid TCNQ-DCNQLtype acceptor has also been obtained. The cyclic voltammetzic data of the novel acceptors reveal two different behaviors for theae molecules. The WNQ-type ...
