Recommanded Product: 11-Bromoundecanoic acid. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 11-Bromoundecanoic acid, is researched, Molecular C11H21BrO2, CAS is 2834-05-1, about Conversion of curved assemblies into two dimensional sheets. Author is Deshmukh, Gunvant; Krishnamoorthy, Kothandam.
The design and preparation of organic two dimensional (O2D) sheets and their conversion to curved nanostructures is in its infancy. To convert a flat structure into a curved structure, the mol. must have multiple interaction possibilities and an in-built twist. The conjugated small mol. iso-Indigo (i-Indigo) comprises two Ph rings that are twisted (the dihedral angle is 15°) at the junction. The i-Indigo has been connected with moieties that impart hydrogen bonding and van der Waals interactions. Due to the presence of the π cloud in i-Indigo, π-π interactions are also present in the mol. While all three interactions are in operation, rings and toroids are formed. Upon addition of hydrogen bonding competing solvents, the rings and toroids unravel to form O2D sheets. Control mols. that don’t have hydrogen bonding moieties and π-π interactions form random assemblies. Please note that the rings, toroids and O2D sheets are formed in a single solvent by simple dissolution, unlike previous approaches that involve multiple steps and solvents.
