title: Highly electron-donating 3,3'-diaryl-1,1'-bi(isobenzofuran)s synthesized by photochemical exocyclic [2 + 2 + 2] cycloaddition.
abstract: Facile photochemical exocyclic [2 + 2 + 2] cycloaddition produced a series of electron-donating 1,1'-bi(isobenzofuran)s having various aryl groups at the 3,3' positions. The 1,1'-bi(isobenzofuran) skeleton with a highly coplanar structure is a useful building unit to construct the narrow bandgap pi-conjugated systems with low oxidation potentials.
