A new method for assessing the topol. of metallosupramol. assemblies using pyrene-appended ligands is reported. Two potentially tetradentate ligands containing one (L1 = I) and two (L2 = II) terminal pyrene moieties were synthesized and their complexes with Cu+ and Cd2+ were characterized. Photophys. measurements demonstrate that in [Cu2(L1)2]2+, [CdL1]2+ and [Cu2(L2)2]2+ the emission spectra are dominated by monomeric emission but in the cadmium complex of L2 (the pyrene units are in close proximity) a quenching of the luminescence coupled with weak emission at 540 nm is indicative of excimer formation. This study involved multiple reactions and reactants, such as 2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5Synthetic Route of C18H11BrO).
2-Bromo-1-(pyren-1-yl)ethanone (cas: 80480-15-5) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. Bromine-containing agents predominate because not only are they more efficient than similar chlorine-containing species, but also the high atomic weight of bromine ensures that it is present in a high mass fraction within most organobromine compounds.Synthetic Route of C18H11BrO
