These compounds were found to possess near-infrared absorption and emission profiles in the 710 to 770 nm domain and exhibit quantum yield values up to 14%. X-ray diffraction analysis revealed that heavier group 13 bis(phenolate) aza-DIPY chelates possessed octahedral geometries with either THF or pyridine groups occupying the axial positions as opposed to the tetrahedral geometry of the boron chelate.Molecules (Basel, Switzerland)8256https://www.ebi.ac.uk/biostudies/studies/S-EPMC9737893biostudies-literatureSynthetic Exploration of Bis(phenolate) Aza-BODIPYs and Heavier Group 13 Chelates.PMC9737893Lummis PALuong NTCNeal MJMontgomery TDKelly JCJamrom JLane AMChase DTBloomfield AJfalseSynthetic Exploration of Bis(phenolate) Aza-BODIPYs and Heavier Group 13 Chelates.A series of boron, aluminum, gallium, and indium chelates containing the underexplored bis(phenolate) aza-dipyrromethene (aza-DIPY) core were prepared.
