In 2022,Miki, Ryotaro; Yamaki, Tsutomu; Uchida, Masaki; Natsume, Hideshi published an article in Colloids and Surfaces, A: Physicochemical and Engineering Aspects. The title of the article was 《Hydrogen peroxide-responsive micellar transition from spherical to worm-like in cetyltrimethylammonium bromide/3-fluorophenylboronic acid/fructose system》.SDS of cas: 768-35-4 The author mentioned the following in the article:

In this study, we successfully prepared a novel hydrogen peroxide (H2O2)-responsive micellar system, whose viscosity drastically changes depending on H2O2 levels. The cationic surfactant cetyltrimethylammonium bromide (CTAB)/3-fluorophenol (3FPhOH) and CTAB/3-fluorophenylboronic acid (3FPBA) systems exhibited high viscosity. The viscosity of the CTAB/3FPBA system significantly decreased with the addition of fructose (Fru). The zero-shear viscosity of the CTAB/3FPBA/Fru system with 40 mM H2O2 increased 4 x 104-fold in comparison to that without H2O2. We confirmed that both the CTAB/3FPhOH and CTAB/3FPBA/Fru with H2O2 systems form worm-like micelle (WLM) structures based on their rheol. properties. The results of dynamic light scattering measurements supported the micellar transition with the addition of H2O2. We successfully demonstrated H2O2-responsive micellar transition from spherical/shorter rod-like micelles to long WLMs. We utilized the two reactions in the CTAB-based micellar system to control micellar transitions and viscosities: (i) Phenylboronic acid (PBA) forms a reversible cyclic ester structure with Fru and (ii) PBA reacts with H2O2to convert phenol. In the part of experimental materials, we found many familiar compounds, such as (3-Fluorophenyl)boronic acid(cas: 768-35-4SDS of cas: 768-35-4)

(3-Fluorophenyl)boronic acid(cas: 768-35-4) can be used to make novel liquid crystalline fluorobiphenylcyclohexenes and difluoroterphenyls by palladium-catalyzed cross-couplings also used in the synthesis of o-phenylphenols as potent leukotriene B4 receptor agonists.SDS of cas: 768-35-4

Sun, Bangjin; Tong, Kai-Ning; Chen, Xing; He, Jian-Li; Liu, Han; Fung, Man-Keung; Fan, Jian published an article in 2021. The article was titled 《A universal thermally activated delayed fluorescent host with short triplet lifetime for highly efficient phosphorescent OLEDs with extremely low efficiency roll-off》, and you may find the article in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices.Product Details of 768-35-4 The information in the text is summarized as follows:

Triplet-involved quenching processes lead to significant efficiency roll-off in phosphorescent organic light-emitting diodes (OLEDs). Thermally activated delayed fluorescent (TADF) materials can reduce the triplet exciton d. in the emitting layer (EML) via the up-conversion of triplet into singlet exciton. However, the effect of the triplet lifetime of TADF hosts on efficiency roll-off is still under-researched. Inspired by the fast spin-flip process in TADF with a small singlet-triplet energy gap, we herein reported a triazine-carbazole hybrid (Trz-PhCz) with a short triplet lifetime, and extremely low efficiency roll-offs were achieved for green, yellow, orange and red OLEDs with external quantum efficiencies (EQEs) over 20% at 10 000 cd m-2. Particularly, the optimized orange device showed a record-high maximum EQE of 31.4%, and 25.5% at 10 000 cd m-2. Furthermore, unprecedented high PEmaxs of 111.8 lm W-1 and 98.9 lm W-1 were obtained for Ir(ppy)2(acac)- and PO-01-based devices, resp. Notably, a two-color white OLED based on a single host Trz-PhCz also showed a remarkably high maximum power efficiency (PEmax) of 102.5 lm W-1 with the Commission Internationale de l’Eclairage (CIE) of (0.42, 0.48). So, the Trz-PhCz-hosted phosphorescent OLEDs showed state-of-the-art device performance, and this work provided insight into the design of efficient TADF host materials via controlling their triplet lifetime for practical applications.

Synthetic Route of C6H6BFO2 The author mentioned the following in the article:

The Suzuki-Miyaura cross-coupling reactions of bromoalkenes R(X)C=C(R1)R2 (R = C6H5, Br; R1 = C6H5, 4-FC6H4; R2 = C6H5, 4-FC6H4; X = Br) with fluorophenylboronic acids R3C6H4B(OH)2 (R3 = 2-F, 3,4-(F)2, 2,4,6-(F)3, etc.) afforded 17 fluorinated tetraphenylethene (FTPE) compounds RC(R3)=C(R1)R2 that have only fluorine substituent(s) directly on the tetraphenylethene (TPE) core with different numbers and substitution positions of the fluorine atom(s). The X-ray structures of four FTPEs show that these FTPE derivatives have C-H…F and C-H…π hydrogen bonds in the crystal packing. DFT calculations indicate that both the HOMOs and LUMOs of the FTPEs essentially have lower energy levels than those of the parent TPE, and the energy gaps are highly dependent on the substitution pattern. These FTPEs exhibit aggregation-induced emission characteristics similar to most TPE derivatives but the aggregation process was found to be gradual and time-dependent. The emission wavelengths of both aggregates from tetrahydrofuran/H2O and solids, and the corresponding emission quantum yields of the solid samples vary with different substitution patterns. In addition, two examples of these FTPEs show reversible mechanofluorochromic and thermofluorochromic properties (the latter was only shown on silica gel), while the parent TPE does not exhibit mechanochromism under the same conditions. In addition to this study using (3-Fluorophenyl)boronic acid, there are many other studies that have used (3-Fluorophenyl)boronic acid(cas: 768-35-4Synthetic Route of C6H6BFO2) was used in this study.

Dodson; Weiss, Michael A. published an article in 2021. The article was titled 《Insertion of a synthetic switch into insulin provides metabolite-dependent regulation of hormone-receptor activation》, and you may find the article in Proceedings of the National Academy of Sciences of the United States of America.COA of Formula: C6H6BFO2 The information in the text is summarized as follows:

Insulin-signaling requires conformational change: whereas the free hormone and its receptor each adopt autoinhibited conformations, their binding leads to structural reorganization. To test the functional coupling between insulins hinge opening and receptor activation, we inserted an artificial ligand-dependent switch into the insulin mol. Ligand-binding disrupts an internal tether designed to stabilize the hormone native closed and inactive conformation, thereby enabling productive receptor engagement. This scheme exploited a diol sensor (meta-fluoro-phenylboronic acid at GlyA1) and internal diol (3,4-dihydroxybenzoate at LysB28). The sensor recognizes monosaccharides (fructose > glucose). Studies of insulin-signaling in human hepatoma-derived cells (HepG2) demonstrated fructose-dependent receptor autophosphorylation leading to appropriate downstream signaling events, including a specific kinase cascade and metabolic gene regulation (gluconeogenesis and lipogenesis). Addition of glucose (an isomeric ligand with negligible sensor affinity) did not activate the hormone. Similarly, metabolite-regulated signaling was not observed in control studies of 1) an unmodified insulin analog or 2) an analog containing a diol sensor without internal tethering. Although secondary structure (as probed by CD) was unaffected by ligand-binding, heteronuclear NMR studies revealed subtle local and nonlocal monosaccharide-dependent changes in structure. Insertion of a synthetic switch into insulin has thus demonstrated coupling between hinge-opening and allosteric holoreceptor signaling. In addition to this foundational finding, our results provide proof of principle for design of a mechanism-based metabolite-responsive insulin. In particular, replacement of the present fructose sensor by an analogous glucose sensor may enable translational development of a smart insulin analog to mitigate hypoglycemic risk in diabetes therapy.
