Synthesis and Spectroscopic Properties of [2.2]Quinquethiophenophane as an Ideal π-Dimer Model
摘要:
[GRAPGICS]The title compound has been synthesized as the first oligothiophenophane that has the typical stacking structure of a layered cyclophane and can behave as an ideal pi -dimer model.
α,ω-Bis(quinquethienyl)alkanes as a π-Dimer Model of Polythiophene
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.
