SDS of cas: 74305-48-9On March 31, 2003, Lucht, S.; Neher, D.; Miteva, T.; Nelles, G.; Yasuda, A.; Hagen, R.; Kostromine, S. published an article in Liquid Crystals. The article was 《Photoaddressable polymers for liquid crystal alignment》. The article mentions the following:

The authors demonstrate reversible photoinduced in situ reorientation of low mol. mass liquid crystals (LCs) by means of photoaddressable polymers (PAPs). These polymers contain mesogenic azobenzene side chains optimized to reorient cooperatively and effectively upon illumination with polarized light. Various low mol. mass LCs were introduced between two PAP layers and these sandwich devices were tested with respect to stability and reversibility of photoinduced orientation. Dissolution of the PAP layer by the low mol. mass LC was observed for several material combinations and systematically investigated. Different anisotropic dyes were added as fluorescence markers in order to monitor the photoinduced LC orientation. With an optimized material combination, more than 10 reversible reorientation processes could be realized with polarized light of either 514 or 405 nm wavelength, without any reduction in alignment quality. Further, microscopic polarized fluorescence patterns could be produced and erased within short exposure times. In the part of experimental materials, we found many familiar compounds, such as 4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9SDS of cas: 74305-48-9)

4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9) belongs to esters. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. SDS of cas: 74305-48-9

《Effect of external electrical field on phase behavior and morphology development of polymer dispersed liquid crystal》 was written by Yang, Dianzhi; Lin, Jiaping; Li, Tao; Lin, Shaoliang; Tian, Xiaohui. Recommanded Product: 74305-48-9 And the article was included in European Polymer Journal on August 31 ,2004. The article conveys some information:

Phase diagrams for mixtures of liquid crystal (LC)/monomer with and without an external elec. field applied have been established using polarized light microscope (PLM). The (isotropic + nematic) coexistent phase region and (isotropic + isotropic) phase boundary of LC/monomer mixtures were observed to shift upward to higher temperatures when the external elec. field exists. The elec. field applied during the crosslinking polymerization has a significant influence on the phase diagrams for the LC/polymer(E 51) mixtures by rendering the coexistent phase regions shift upward to higher temperatures The influence of the external elec. field on the processes of the isotropic-isotropic phase separation and liquid crystal ordering in PDLC formation has also been investigated. Both the processes could be highly accelerated by the elec. field. In the experiment, the researchers used many compounds, for example, 4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9Recommanded Product: 74305-48-9)

Frunza, Ligia; Zgura, Irina; Ganea, Constantin Paul; Schonhals, Andreas published their research in Journal of Molecular Liquids on August 1 ,2022. The article was titled 《Molecular dynamics of alkyl benzoate liquid crystals in the bulk state and in the surface layer of their composites with oxide nanopowders》.SDS of cas: 74305-48-9 The article contains the following contents:

This paper presents the results concerning monotropic nematic liquid crystals 4-pentylphenyl 4′-alkyl benzoate (5PnB) (n = 3 or 5 carbon atoms in the alkyl chain). Their mesophase properties were supported by images of the polarized optical microscopy. Mol. dynamics in the bulk samples or in the composites prepared with aerosil A380 was investigated by broadband dielec. spectroscopy in a large temperature range, appropriately chosen. Thermo gravimetric and IR investigations were addnl. performed. The data were compared with those of structurally related nematics like cyanophenyl pentyl benzoates, which have a cyan group instead of the pentyl chain. The dielec. spectra of the bulk 3P5B and 5P5B demonstrate a dielec. behavior with several relaxation processes as expected for nematic liquid crystals. The temperature dependence of the relaxation rates (and of the dielec. strength) seems to have two distinguished regimes. Thus, in the isotropic state, at higher temperatures the data obey the Vogel-Fulcher-Tammann law, whereas an Arrhenius law is fitted at lower temperature, in a close similarity to the behavior of a constrained dynamic glass transition. Samples with a high d. of silica (larger than 7 g aerosil/1 g of 5PnB) were prepared to observe a thin layer adsorbed on the particle surface, it was estimated that almost each guest 5PnB mol. interacts with the aerosil surface. For the composites only one main relaxation process is observed at frequencies much lower than those for the corresponding bulk, which was assigned to the dynamics of the mols. in the surface layer. IR spectroscopy shows that these mols. interact with the surface by the ester carbonyl group leading to the monolayer self-assembly at liquid-solid interface. We note once more the importance of the functional unit(s) for the interaction with the hydroxyl groups on the aerosil surface.

Bradshaw, M. J.; Raynes, E. P.; Fedak, I.; Leadbetter, A. J. published an article on January 31 ,1984. The article was titled 《A correlation between short range smectic-like ordering and the elastic constants of nematic liquid crystals》, and you may find the article in Journal de Physique (Paris).Quality Control of 4-n-Pentylphenyl-4-pentylbenzoate The information in the text is summarized as follows:

The measurements of the bend (k33) and splay (k11) elastic constants and the amplitude of the smectic-like local ordering (obtained using x-ray diffraction techniques), were made for a wide range of nematogens. The results reveal a strong correlation between k33/k11 and the strength of the smectic-like local ordering. This correlation applies to nematogens with either bilayer or monolayer structures, irresp. of whether or not they exhibit a smectic phase. These results have been rationalized in more detail in terms of a recent theor. model which calculated the elastic constants as a function of smectic-like local ordering. In addition to this study using 4-n-Pentylphenyl-4-pentylbenzoate, there are many other studies that have used 4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9Quality Control of 4-n-Pentylphenyl-4-pentylbenzoate) was used in this study.

In 1984,Liquid Crystals and Ordered Fluids included an article by Bone, M. F.; Price, A. H.; Clark, M. G.; McDonnell, D. G.. SDS of cas: 74305-48-9. The article was titled 《Dielectric studies of monoester and diester nematogens》. The information in the text is summarized as follows:

The permittivities of several monoester nematogens were studied in the nematic and isotropic phases at frequencies ≤18 GHz. The dielec. relaxations observed in the nematic phase agreed with theor. predictions for a rigid nematogen. Values for the nematic order parameter and the angle between the “”long axis”” of the mol. and its elec. dipole were estimated from the data, and the definition of the “”long axis”” in the mol. theory of nematics is discussed. Two distinct relaxation frequencies were observed in the isotropic phase of substituted Ph benzoates, probably due to anisotropic rotational mol. diffusion, indicative of residual nematiclike short-range order. This interpretation is supported by quant. comparison with nematic phase data, and by data on a benzene solution and the nonnematic Ph benzoate parent. Data on cyclohexane carboxylate esters reveal interesting similarities and contrasts with the benzoate esters. Recent developments in liquid-crystal materials for 2-frequency-addressed devices are considered in the context of the data on monoesters together with studies of dielec. relaxation in monoester/diester mixtures4-n-Pentylphenyl-4-pentylbenzoate(cas: 74305-48-9SDS of cas: 74305-48-9) was used in this study.

Quality Control of 4-n-Pentylphenyl-4-pentylbenzoateOn September 30, 1987 ,《Reentrant nematic and injected smectic behavior in binary mixtures including those of terminally nonpolar compounds》 was published in Molecular Crystals and Liquid Crystals. The article was written by Chan, L. K. M.; Gray, G. W.; Lacey, D.; Srithanratana, T.; Toyne, K. J.. The article contains the following contents:

Some examples of injected smectic behavior (SB and SA) for binary mixtures of strong terminally polar mesogens with a range of terminally nonpolar esters are presented. Variations in the strength of the injected behavior are discussed. Mixtures of terminally nonpolar 4,4″”-dialkyl-2′-fluoro-p-terphenyls (I) with CN-substituted mesogens were also studied and provide an example of injection of SA and SE phases. Binary mixtures consisting solely of homologs of I can exhibit reentrant nematic behavior, providing further evidence that reentrant phenomena are not a special feature of terminally polar mesogens and their mixtures An isomeric mixture of 2 compounds of I also gives an injected SC phase, and enhanced SC properties are recorded for other mixtures of I. Mixtures involving alkyl/alkoxy analogs of I also provide examples of SC phase injection or enhancement, and in 1 case some evidence for injected SI behavior.
