α‐Oligofurans: Molecules without a Twist

Abstract

Be planar! The planar oligofurans (see picture, lower; C gray, H white, O red) are, despite a lack of solubilizing alkyl groups, quite soluble. They are also highly fluorescent and surprisingly stable, and might give the oligothiophenes (upper; S yellow) a run for their money when seeking applications in organic electronics.
