(Chemical Equation Presented) Employing two consecutive cyclization reactions, benzo[1,2-b:4,5-b′]bis[b]benzochalcogenophenes, which are π-extended heteroarenes, were efficiently synthesized. Their electronic and crystal structures were elucidated on the basis of UV-vis spectra, electrochemical measurements, and X-ray structural analyses.
