Hydrolytic stability of nitrogenous-heteroaryltrifluoroborates under aqueous conditions at near neutral pH was written by Li, Ying;Asadi, Ali;Perrin, David M.. And the article was included in Journal of Fluorine Chemistry in 2009.Application of 1072951-54-2 This article mentions the following:

The hydrolytic stability of heteroaryltrifluoroborates under physiol. conditions has been analyzed by ¹⁹F NMR spectroscopy and is found to be greatly enhanced by the presence of endocyclic ring nitrogens. Stability is further enhanced by the presence of exocyclic electron withdrawing substituents. As with aryltrifluoroborates, NMR anal. suggests that the hydrolysis proceeds via single rate-determining step reflecting loss of the first fluoride atom. The stability of these complexes is significant both in terms of metal catalyzed cross-coupling reactions as well as the potential for generating boronic acid based ¹⁸F-PET imaging agents. In the experiment, the researchers used many compounds, for example, (2,6-Dichloropyridin-4-yl)boronic acid (cas: 1072951-54-2Application of 1072951-54-2).

(2,6-Dichloropyridin-4-yl)boronic acid (cas: 1072951-54-2) belongs to pyridine derivatives. Pyridine has a conjugated system of six 锜?electrons that are delocalized over the ring. The molecule is planar and, thus, follows the H鐪塩kel criteria for aromatic systems. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Application of 1072951-54-2

Efficient and stable deep blue thermally activated delayed fluorescent molecules based on a bipyridine acceptor core was written by Cheng, Cong;Jiang, Yongshi;Wang, Haonan;Lou, Weiwei;Zhu, Yunhui;Deng, Chao;Wang, Dan;Tsuboi, Taiju;Li, Guijie;Zhang, Qisheng. And the article was included in Journal of Materials Chemistry C: Materials for Optical and Electronic Devices in 2021.Application In Synthesis of (2,6-Dichloropyridin-4-yl)boronic acid This article mentions the following:

High efficiency and low cost organic light-emitting diodes (OLEDs) employing thermally activated delayed fluorescent (TADF) materials have attracted great attention. However, combining high quantum efficiency and stability is still challenging for deep blue TADF OLEDs. Here, we report a type of novel blue TADF emitter consisting of a bipyridine weak acceptor and four carbazole donors. These D-A-type emitters exhibit a high fluorescence rate of 9.8 x 10⁷ s^-1 and a small ΔE_ST of 0.08 eV owing to the energy approach of the frontier orbitals on the isolated D/A segments and adequate overlap of the frontier orbitals in the D-A systems. The organic light-emitting diodes containing these emitters offer deep blue emission with a half-width of 58 nm. High external quantum efficiencies of 15.3% and 18.7% are achieved in devices with emission maxima at 459 nm and 471 nm, resp. In comparison to the structurally analogous TADF emitters with a π-bridge between the donor and acceptor moieties, the bipyridine/carbazole derivatives with a compact “donors-surrounding-acceptor” structure exhibit superior stability in both photoluminescence and electroluminescence. In the experiment, the researchers used many compounds, for example, (2,6-Dichloropyridin-4-yl)boronic acid (cas: 1072951-54-2Application In Synthesis of (2,6-Dichloropyridin-4-yl)boronic acid).

(2,6-Dichloropyridin-4-yl)boronic acid (cas: 1072951-54-2) belongs to pyridine derivatives. Pyridine has a dipole moment and a weaker resonant stabilization than benzene (resonance energy 117 kJ·mol−1 in pyridine vs. 150 kJ·mol−1 in benzene). Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Application In Synthesis of (2,6-Dichloropyridin-4-yl)boronic acid
