Enhancing conformational flexibility of dendronized triphenylene via diethylene glycol linkers lowers transitions of helical columnar, Frank-Kasper, and quasicrystal phases was written by Imam, Mohammad R.;Peterca, Mihai;Xiao, Qi;Percec, Virgil. And the article was included in Giant in 2022.HPLC of Formula: 111-46-6 This article mentions the following:
A library of triphenylene (Tp) dendronized with self-assembling dendrons via a diethylene glycol linker was synthesized and the corresponding self-organizations were analyzed. They self-organize via a crown conformation in helical columns and spherical helixes that produce hexagonal columnar, Frank-Kasper and soft quasicrystal assemblies. The same self-organizations are produced in the absence of the diethylene glycol linker except that the phase transitions and isotropization temperatures occur at lower temperatures in the presence of the linker. The incorporation of the flexible diethylene glycol linker induces also strong π-π stacking in helical columns. Spherical helixes are spherical distorted short fragments of helical columns and therefore the same principles determine the thermal stability of the hexagonal columnar and of Frank-Kasper and quasicrystal assemblies except that the length of the supramol. backbone is much longer in helical columns. A comparison of these systems with side-chain liquid crystals indicates that supramol. dendrimers are stabilized by extended supramol. backbone conformations. This result suggests pathways to molecularly engineer phase transitions of supramol. dendrimers self-organized from crown conformations. In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6HPLC of Formula: 111-46-6).
2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.HPLC of Formula: 111-46-6
