The design and synthesis of a series bent-core materials base on a 3,4′-biphenyldiol central core containing salicylaldimine-based and two terminal tetradecyloxy tails are reported. In addition, the effects of lateral substituents (R = F and Cl) at the biphenyl core into 3′-position are examined These substituents have a strong influence in reducing the clearing temperatures and increasing temperature range of SmCP phase. Upon cooling process the isotropic liquid, compound SB-Cl exhibits the lowest clearing transition temperature of 180°C and the widest SmCP phase range of 129°C. The mesophase behavior were investigated by polarizing optical microscopy (POM), differential scanning calorimetry (DSC), X-ray diffraction (XRD), and electro-optical (EO) measurements in the mesophase temperature range. In the experiment, the researchers used many compounds, for example, 3-[(2-Tetrahydropyranyl)oxy]phenylboronic Acid (cas: 1287777-05-2HPLC of Formula: 1287777-05-2).
3-[(2-Tetrahydropyranyl)oxy]phenylboronic Acid (cas: 1287777-05-2) belongs to tetrahydropyran derivatives. Numerous natural products have tetrahydropyran skeleton as the building block for designing new natural products and their derivatives e.g. aplysiatoxins, avermectins, oscillatoxins, talaromycins, latrunculins and acutiphycins. Pyran derivatives such as pyran flavonoids are biologically important. Monosaccharides containing six-membered rings are called pyranose.HPLC of Formula: 1287777-05-2
