Two novel macromol. constitutional isomers have been self-assembled from previously unreported terpyridine ligands in a three-component system. The terpyridine ligands were synthesized in high yields via a key Suzuki coupling. Restrictions of the possible outcomes for self-assembly ultimately provided optimum conditions for isolation of either a mol. bowtie or its isomeric butterfly motif. These isomers have been characterized by ESI-MS, TWIM-MS, 1H NMR, and 13C NMR. Notably, these structural isomers have remarkably different drift times in ion mobility separation, corresponding to different sizes and shapes at high charge states. In the experiment, the researchers used many compounds, for example, Dimethyl 4,5-dibromophthalate (cas: 859299-66-4Synthetic Route of C10H8Br2O4).
Dimethyl 4,5-dibromophthalate (cas: 859299-66-4) belongs to organobromine compounds. Organo bromine compounds are versatile compounds and are widely used in diverse fields. Organo bromine derivatives are used in the dye sector, as an indicator in analytical chemistry (Bromothymol blue is a popular indicator). 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 C10H8Br2O4
