摘要
Novel extended BODIPYs fused with bicyclo rings were synthesized from bicyclopyrroles by combining Knoevenagel condensation, Suzuki coupling, and O-chelation. The absorption maxima of the BODIPYs ranged from the visible to near-infrared region and the compounds showed good solubility in organic solvents. The solubility of the bicycloBODIPY with 2-naphthyl groups at the alpha-position of the pyrrole units was particularly high. Heating converted distyryIBODIPY with bicyclo[2.2.2]octene to benzoBODIPY with absorption (748.5 nm) and fluorescence (775.0 nm) in the near-infrared region. (C) 2019 Elsevier Ltd.
