title: Synthesis and spectroscopic properties of β,β'-dibenzo-3,5,8-triaryl-BODIPYs.
abstract: A series of β,β'-bicyclo-3,5-diaryl-BODIPYs were synthesized from the corresponding β,β'-bicyclo-3,5-diiodo-BODIPYs (1a,b)viaPd(0)-mediated Suzuki cross-coupling reactions in 82-92% yields. Subsequent aromatization with DDQ afforded the corresponding β,β'-dibenzo-aryl-BODIPYs, which showed red-shifted absorptions and emissions in the near-IR range. The dibenzo-appended BODIPYs showed characteristic1H-,13C-,11B- and19F-NMR shifts, and nearly planar conformations by X-ray crystallography.
