Using 3-phenyl-5-(5-phenyl-1H-pyrrol-3-yl)-1,2,4-oxadiazole, BODIPYs with the oxadiazole groups at the 1,7-positions were prepared and their photophysical properties were characterized. The method employs 2,4-diphenyl substituted pyrrole and various aromatic aldehydes under solvent-free conditions. Due to the attachment of the oxadiazole groups at the 1,7-positions, the BODIPYs show long-wavelength absorption and emission in the near-infrared region. © 2022 The Royal Society of Chemistry
