Ogoshi, Tomoki; Maruyama, Keisuke; Sakatsume, Yuma; Kakuta, Takahiro; Yamagishi, Tada-aki; Ichikawa, Takahiro; Mizuno, Motohiro published the article 《Guest Vapor-Induced State Change of Structural Liquid Pillar[6]arene》. Keywords: guest Vapor state change structural liquid pillar arene NMR.They researched the compound: 1-Bromoundecane( cas:693-67-4 ).Safety of 1-Bromoundecane. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:693-67-4) here.
State change is a key phenomenon in materials science. We report the first observation of vapor-responsive reversible structural liquid-to-solid and solid-to-structural liquid state changes. We observed that a macrocyclic compound, a pillar[6]arene derivative bearing 12 n-hexyl substituents, is a room temperature structural liquid with unique properties. Formation of a host-guest complex between the pillar[6]arene cavity and the n-hexyl substituent results in a structural liquid with nanoscale structural heterogeneities. The structural liquid solidifies when exposed to competitive cyclohexane guest vapor, whereupon cyclohexane replaces the n-hexyl substituents in the pillar[6]arene cavity and the n-hexyl substituents located outside of the cavity crystallize into distinct nanolayer assemblies. The solid reverts back to the structural liquid when the cyclohexane guest is removed through heating under reduced pressure because of rethreading of the n-hexyl substituents into the cavity. The structural liquid-to-solid and solid-to-structural liquid changes are reversible through the uptake and release of cyclohexane guest vapor.
There is still a lot of research devoted to this compound(SMILES：CCCCCCCCCCCBr)Safety of 1-Bromoundecane, and with the development of science, more effects of this compound(693-67-4) can be discovered.
