A new BODIPY system displaying an intramol. π-π-interaction was synthesized and studied. When the selenium center was oxidized, the substituted Ph group undergoes π-π stacking with one side of the BODIPY core. The oxidized form showed, not only a down-field shift in the NMR peak, but also splitting due to geometrical changes that arise when going from Cs to C1. The compound was characterized by X-ray diffraction; DFT methods helped elucidate the influence of the unexpected π-π stack and its connection to the photophys. properties imparted by the Se oxidation In the experiment, the researchers used many compounds, for example, 5-Bromothiophene-3-carbaldehyde (cas: 18791-79-2Computed Properties of C5H3BrOS).
5-Bromothiophene-3-carbaldehyde (cas: 18791-79-2) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. The reactivity of organobromine compounds resembles but is intermediate between the reactivity of organochlorine and organoiodine compounds. For many applications, organobromides represent a compromise of reactivity and cost.Computed Properties of C5H3BrOS
