2-Bromo-1,10-phenanthroline (cas: 22426-14-8) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. 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.Related Products of 22426-14-8

Three isomeric phenanthroline compounds, 2-DP, 3-DP, and 5-DP, are constructed by incorporating 4-(2,2-diphenylvinyl)phenyl unit into 2-, 3-, and 5-positions of phenanthroline. This approach functionalizes these compounds to exhibit different solvatochromism effects and metal-ion sensing abilities. 2-DP shows no obvious sensitivity for proton solvent and metal ions, but it’s quite the opposite for 3-DP and 5-DP. 3-DP possesses higher selectivity and sensitivity to Zn2+ than 5-DP to Zn2+, with a limit of detection down to 10-8 M. The d. function theory calculations reveal that their different sensing behaviors are related to their steric hindrance and electronic effects. 2-DP, 3-DP, and 5-DP all exhibit aggregation-induced enhanced emission (AIEE), in which the luminescence (PL) enhancement of 2-DP is the biggest in aggregated state. Probably the mol. torsion degree is responsible for their different AIEE behaviors, which is supported by the x-ray structural anal. The isomer engineering for phenanthroline provides a simple method to enhance the selectivity and sensitivity to metal ions, and to optimize solid-state luminescence properties. In the experiment, the researchers used many compounds, for example, 2-Bromo-1,10-phenanthroline (cas: 22426-14-8Related Products of 22426-14-8).
