摘要：

[GRAPHICS] A series of the title dimeric quinquethiophenes linked with a di- to hexamethylene spacer was synthesized and examined as a pi-dimer model of polythiophene. Upon two-electron oxidation with iron(III) chloride in dichloromethane, they readily form intramolecular pi-dimer species, except for the dimethylene-linked dimer that cannot be bent into a pi-stacked structure.
