The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 4-(((1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl)oxy)-4-oxobutanoic acid(SMILESS: CC(C)[C@@H]1CC[C@@H](C)C[C@H]1OC(=O)CCC(O)=O,cas:77341-67-4) is researched.Reference of 8-Bromoguanine. The article 《Tuning the colour of glassy cholesteric liquid crystals using copolymerization of two left-handed menthyl- and cholesteryl-based mesogenic monomers》 in relation to this compound, is published in Liquid Crystals. Let’s take a look at the latest research on this compound (cas:77341-67-4).
A new series of polysiloxane glassy cholesteric liquid crystal copolymers with menthyl- and cholesteryl-based mesogenic units in the side chains, P-MtxChy denoted as (x, y expresses the molar ratio of monomers and in Mt and Ch copolymeric synthesis, and x + y = 7.) were successfully synthesized by hydrosilylation reaction. The mesomorphic properties and phase behaviors were studied by differential scanning calorimetry, polarising optical microscopy and X-ray diffraction. Optical properties were investigated by the UV-VIS spectrum. Using the volume-excluding action of mesogenic units in side chains, we obtained glassy cholesteric liquid crystal copolymers. By varying molar ratio of Mt and Ch in copolymers, the helical pitch was adjusted into visible light region. With the increase of Mt, the maximum reflection wavelength off normal 8° shifted from 548 nm of P-Mt3Ch4 to 650 nm of P-Mt4Ch3 to 872 nm of P-Mt5Ch2, and the reflected colors changed from green to red. These well-oriented glassy films have shown good morphol. stability below the glass-transition temperature (Tg) for more than a year.
After consulting a lot of data, we found that this compound(77341-67-4)HPLC of Formula: 77341-67-4 can be used in many types of reactions. And in most cases, this compound has more advantages.
