摘要：

Novel cross-conjugated oligomers composed of p-quinone methides and thiophenes, synthesized up to tetramer, possess substantially high electron affinity (CV). Alkali metal reduction of the dimer yields a stereoisomeric mixture of stable dianions, and protonation with trifluoroacetic acid generates the corresponding monocation and dication depending on acid strength.
