We report the synthesis and properties of a series of novel triphenylenedicarboxyimides and thioimides (R = decyl) to probe the effect of thionation on the formation of columnar mesophases. These materials display broad columnar mesophases and high clearing points and self-associate in solution to form dimers. Overall, thionation improved the self-assembly in solution and led to a stabilization of the columnar mesophase. Furthermore, increasing the thionation of these materials led to a lowering of the LUMO energy level and a narrowing of the HOMO-LUMO gap. In the experiment, the researchers used many compounds, for example, Dimethyl 4,5-dibromophthalate (cas: 859299-66-4Recommanded Product: 859299-66-4).
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). The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Recommanded Product: 859299-66-4
