title: Synthesis of sexithiophene-bridged cage compound: a new class of three-dimensionally expanded oligothiophenes.
abstract: A bicyclo-type cage-shaped compound consisting of three sexithiophenes was successfully synthesized and characterized by NMR, HRMS, and X-ray crystallographic analysis. The strained cage architecture was reflected in the blue-shifted absorption spectrum relative to its linear analogue. Intramolecular interaction between three-dimensionally fixed sexithiophenes was suggested by electrochemical analysis.
