일반 설명
Dibenzo-24-crown-8 is a macrocyclic compound that is used as a versatile reagent in organic synthesis due to its ability to form complexes with metal ions and enhance their solubility and reactivity. It is also used as a phase-transfer catalyst in various organic reactions, such as the synthesis of organic carbonates and the alkylation of phenols.
애플리케이션
Dibenzo-24-crown-8 can be used as a molecular transporter in the formation of [1]rotaxanes with thiazolium-based mono- and tris-branched ammonium ions. It is also used as a co-solvent and phase-transfer catalyst for cesium fluoride, to the development of a more efficient anhydrous fluorinating system for organic synthesis.

[2]rotaxanes composed of a dibenzo-24-crown-8 wheel (DB24C8) and an axle containing two metal-complexing tetraazamacrocyclic units linked with a p-xylylene bridge, coordinating the same or different metal ions (Ni and/or Cu) are described. A symmetric di-Ni rotaxane crystallizes in the monoclinic

Most attributes of the bulk materials, especially in the solid-state, are directly dictated by a manner by which the molecules are ordered. Thus, it is expected that the possibility of controlling these structural orders would allow predominating some particular physical

"Three methylene spacer" bis(benzimidazolium) derivatives act as a new template for threading dibenzo-24-crown-8 into [2]pseudorotaxanes. In this Article we sought to unveil the difference in the extent of threading of various "three methylene spacer" bis-benzimidazolium moieties based on differences in
