BOIMPYs: Rapid Access to a Family of Red-Emissive Fluorophores and NIR Dyes was written by Patalag, Lukas J.;Jones, Peter G.;Werz, Daniel B.. And the article was included in Angewandte Chemie, International Edition in 2016.Product Details of 15186-48-8 This article mentions the following:

A fundamental, highly fluorescent, and easily accessible scaffold derived from the BODIPY core is reported. The use of benzimidazole as a bridging ligand at the meso position enables the binding of two BF₂ units to provide sufficient rigidity and enhanced electron-withdrawing strength. Absorption and emission events thus take place in the red (λ≈600 nm); the fluorescence quantum yields can reach unity (0.96) and show little dependence on solvent polarity. The synthetic route was shortened to two steps starting from com. available precursors while the preparation is modular and tolerates various pyrrole and benzimidazole moieties. Fluoride replacement by propynyl groups, various halogenations, as well as Knoevenagel-type condensations were applied to extend the versatility of these new photostable fluorophores, which we termed BOIMPYs. In the experiment, the researchers used many compounds, for example, (R)-2,2-Dimethyl-1,3-dioxolane-4-carbaldehyde (cas: 15186-48-8Product Details of 15186-48-8).
