COA of Formula: C18H16FNO2 And the article was included in Journal of Molecular Liquids on April 1 ,2019. The article conveys some information:

Here, we show the method to determine the pressure conditions for liquid crystal restricted in nanochannels. For this purpose, broadband dielec. spectroscopy studies of 4CFPB glass-forming nematic liquid crystal at various pressure conditions and confined in non-intersecting nanopores of mean diameters 6 nm and 8 nm were combined. The pressure dependence of 4CFPB clearing point occurred to be linear and enabled to find pressure conditions in restricted spatial geometry. The pressure evolution of glass transition temperature was non-linear and was described well using the Andersson-Andersson law. Based on the presented results, the temperature-pressure phase diagram was constructed. In the part of experimental materials, we found many familiar compounds, such as 4-Cyano-3-fluorophenyl 4-butylbenzoate(cas: 86776-52-5COA of Formula: C18H16FNO2)

Features of glass transition in liquid crystalline nematic and smectic E, B and IA phases of selected materials observed by means of the polarising microscopy and Fourier transform IR spectroscopy (FTIR) are reported. Evolution of cracking in the glass and a coincidence of its disappearance temperature with the glass transition temperature (Tg) on heating is shown and discussed in the context of processes that occur in the glass. The shape of temperature dependencies of absorption bands is shown as the signature of the glass transition.

SDS of cas: 86776-52-5On September 30, 1984 ,《Synthesis and some properties of 3-fluoro-4-cyanophenyl 4′-n-alkylbenzoates》 was published in Molecular Crystals and Liquid Crystals. The article was written by Sasaki, M.; Takeuchi, K.; Sato, H.; Takatsu, H.. The article contains the following contents:

A series of 3-fluoro-4-cyanophenyl 4′-n-alkylbenzoates, which show monotropic nematic phases, was prepared and their transition temperatures and melting enthalpies were measured. The 3-fluoro-4-cyanophenyl 4′-n-propylbenzoate, 3-chloro-4-cyanophenyl 4′-n-propylbenzoate, and 4-cyanophenyl 4′-n-propylbenzoate were mixed with a nematic mixture (A) of 4-n-alkoxyphenyl 4′-n-alkylcyclohexane-1′-carboxylates. 3-Fluoro-4-cyanophenyl 4′-n-propylbenzoate decreases the N-I transition temperature less, increases the birefringence more, and increases the bulk viscosity less than 3-chloro-4-cyanophenyl 4′-n-propylbenzoate, and reduces the threshold voltage to the greatest extent. The dielec. anisotropies of 3-fluoro-4-cyanophenyl 4′-n-propylbenzoate and 4-cyanophenyl 4′-n-propylbenzoate determined from a series of solutions of the compounds in nematic mixture (A) are 35.9 and 29.6, resp.

《Ionothermal synthesis of crystalline microporous aluminophosphates: Systematic study on the conditions affecting the framework type》 was written by Azim, Muhammad Mohsin; Pensado, Alfonso; Kirchner, Barbara; Gutmann, Torsten; Groszewicz, Pedro B.; Buntkowsky, Gerd; Stark, Annegret. Name: 4-Cyano-3-fluorophenyl 4-butylbenzoate And the article was included in Microporous and Mesoporous Materials on August 31 ,2018. The article conveys some information:

In a systematic study on the synthesis of aluminophosphates (AlPOs) under ionothermal conditions, initially using 1-butyl-3-methylimidazolium bromide ([C4mim]Br) as ionic liquid solvent and structure-directing agent, the effect of the reaction conditions (i.e. molar P/Al, F/Al and ionic liquid/Al ratios, alternative fluoride sources, influence of the ionic liquid’s cation or anion, temperature, reaction time) on the framework type was studied in detail. In [C4mim]Br, the formation of the more thermodynamically stable AEL framework type proceeds via AFI. The framework type can be changed by choosing another anion or cation of the ionic liquid Hence, the successful ionothermal synthesis of the AFI framework AlPO is reported by using either N-ethylpyridinium bromide ([C2py]Br) or 1-butyl-3-methylimidazolium chloride ([C4mim]Cl). The mineralizer [Me4N]F, rather than HF, has been used for the first time as an alternative fluoride source in ionothermal synthesis, which can also affect the framework type. Hence, a very efficient synthesis of the LTA framework type is reported in [C4mim]Br using [Me4N]F. Ab initio mol. dynamics (AIMD) studies showed that the anion bridges between the aluminum atoms of the framework and the cation. The interaction is more favored in the presence of the bromide than the chloride, which may be a clue to the question why the AEL framework is not formed in the chloride-based ionic liquid This study opens several routes to pursue in the future as numerous ionic liquids are available which can be used in ionothermal synthesis. In addition to this study using 4-Cyano-3-fluorophenyl 4-butylbenzoate, there are many other studies that have used 4-Cyano-3-fluorophenyl 4-butylbenzoate(cas: 86776-52-5Name: 4-Cyano-3-fluorophenyl 4-butylbenzoate) was used in this study.

Category: nitriles-buliding-blocksOn November 30, 2012 ,《Isothermal high-pressure studies of 4-cyano-3-fluorophenyl 4-butylbenzoate dynamics near room temperature》 appeared in Physical Review E: Statistical, Nonlinear, and Soft Matter Physics. The author of the article were Rozwadowski, Tomasz; Massalska-Arodz, Maria; Wojnarowska, Zaneta; Paluch, Marian; Juszynska, Ewa; Krawczyk, Jan. The article conveys some information:

For 4-cyano-3-fluorophenyl 4-butylbenzoate, a glass former giving glass of nematic phase at ambient pressure and after rapid pressurizing, isothermal studies of complex dielec. permittivity vs. pressure were performed near room temperature In the previous isobaric experiment, on cooling the nematic phase two super-Arrhenius α relaxations, ascribed to the reorientations of mols. around short axes (main process) and precession of long mol. axes, and β relaxation related to intramol. motions were found. In the present isothermal experiments nematic-smectic phase transition was induced by increasing pressure. Linear pressure dependence of the logarithm of the dielec. relaxation time gives activation volume of ∼70 cm3/mol for liquid crystalline phases and 50 cm3/mol for the isotropic phase. The time-temperature-pressure superposition principle for the α-relaxation process is valid (i.e., a single master curve can be obtained by superpositioning dielec. loss curves measured at various temperatures and pressures). In addition to this study using 4-Cyano-3-fluorophenyl 4-butylbenzoate, there are many other studies that have used 4-Cyano-3-fluorophenyl 4-butylbenzoate(cas: 86776-52-5Category: nitriles-buliding-blocks) was used in this study.
