Germylenes Exhibiting Solid-State Emissions that Extend to NIR

Chemistry. 2023 Jul 23:e202301486. doi: 10.1002/chem.202301486. Online ahead of print.ABSTRACTLow-valent main group compounds that fluoresce in the solid-state were previously unknown. To address this, we investigated room-temperature photoluminescence from a series of crystals of germylenes 3-8 in this article; they exhibited emissions nearly reaching the NIR. Germylene carboxylates (3-8) were synthesized by reacting dipyrromethene-stabilized germylene pyrrolide (2) with carboxylic acids such as acetic acid, trifluoroacetic acid, benzoic acid, p-cyanobenzoic acid, p-nitrobenzoic acid, and acetylsalicylic acid.PMID:37485580 | DOI:10.1002/chem.202301486
