A new approach in which a low symmetry cluster meets a low symmetry ligand to sharply boost the thermal stability of a MOF via addnl. inter-linker interactions is presented for the first time, leading to the successful synthesis of a novel binuclear Co-based MOF, {[Co2(L1)2DMF]·1.5DMF·0.75MeOH·1.5H2O}∞ (H2L1 = 5-(pyridin-3-yl)isophthalic acid, NJU-Bai62: NJU-Bai for Nanjing University Bai group), with exceptional thermal stability of up to 450°.

Application In Synthesis of Pyridin-3-ylboronic acidIn 2020 ,《Recyclable Cu@C3N4-Catalyzed Hydroxylation of Aryl Boronic Acids in Water under Visible Light: Synthesis of Phenols under Ambient Conditions and Room Temperature》 appeared in ACS Sustainable Chemistry & Engineering. The author of the article were Muhammad, Mehwish Hussain; Chen, Xiao-Lan; Liu, Yan; Shi, Tao; Peng, Yuyu; Qu, Lingbo; Yu, Bing. The article conveys some information:

A heterogeneous photocatalyst based on copper-doped g-C3N4 was developed for the oxidative hydroxylation of aryl boronic acids into phenols at room temperature under the irradiation of blue light (460 nm). The reaction proceeded efficiently in water as a green solvent and air as a green oxidant, giving various phenols as products with high yields in a short reaction time. Importantly, this heterogeneous catalyst can be used at least 5 times with the reactivities maintained. A copper-doped g-C3N4 was developed as a heterogeneous photocatalyst for the hydroxylation of aryl boronic acids toward phenols in water under room temperature with the irradiation of blue light. The results came from multiple reactions, including the reaction of Pyridin-3-ylboronic acid(cas: 1692-25-7Application In Synthesis of Pyridin-3-ylboronic acid)

Guo, Yuanqiang; Cao, Yunpeng; Song, Hongjian; Liu, Yuxiu; Wang, Qingmin published an article in 2021. The article was titled 《Photoredox relay-catalyzed gem-difluoroallylation of alkyl iodides》, and you may find the article in Chemical Communications (Cambridge, United Kingdom).Reference of Pyridin-3-ylboronic acid The information in the text is summarized as follows:

Herein, a new example of relay catalysis, using a combination of Mn2(CO)10 and an iridium-based photocatalyst, is reported. In this relay catalytic reaction, the Mn catalyst and iridium-based photocatalyst catalyze the reaction at different stages in the desired sequence under the same reaction conditions, and do not inhibit each other. This convenient method transforms a broad scope of alkyl iodides RI (R = iso-Pr, cyclopentyl, 4-methoxyphenethyl, morpholino, etc.) into the corresponding gem-difluoroalkenes R1C(=CF2)CH2R (R1 = Ph, 2-naphthyl, pyridin-3-yl, etc.) via C(sp3)-C(sp3) bond construction. The protocol has good functional group tolerance and is suitable for the late-stage modification of multifunctional complex mols. In the experiment, the researchers used many compounds, for example, Pyridin-3-ylboronic acid(cas: 1692-25-7Reference of Pyridin-3-ylboronic acid)

Pyridin-3-ylboronic acid(cas: 1692-25-7) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Reference of Pyridin-3-ylboronic acid

Fluorescent small mols. are powerful tools for imaging α-synuclein pathol. in vitro and in vivo. In this work, we explore benzofuranone as a potential scaffold for the design of fluorescent α-synuclein probes. These compounds have high affinity for α-synuclein, show fluorescent turn-on upon binding to fibrils, and display different binding to Lewy bodies, Lewy neurites and glial cytoplasmic inclusion pathologies in post-mortem brain tissue. These studies not only reveal the potential of benzofuranone compounds as α-synuclein specific fluorescent probes, but also have implications for the ways in which α-synucleinopathies are conformationally different and display distinct small mol. binding sites.

Computational simulation is used to investigate the optimal structure, orbital distribution, and physicochem. properties of both mols. Thermal, optical, and electrochem. anal. shows that 26DBFPTPy and 26DBTPTPy possess high thermal stability, deep HOMO energy levels (-7.08 and -6.91 eV), and a high triplet energy (ET) (2.75 and 2.70 eV). Blue PhOLEDs with 26DBFPTPy or 26DBTPTPy as a hole blocking layer (HBL) exhibit a low turn-on voltage (3.0 V) and operating voltage (4.5 V) at 1000 cd m-2. In addition, the blue PhOLEDs with 26DBFPTPy or 26DBTPTPy show superior external quantum efficiencies (24.1 and 23.6%) and power efficiencies (43.9 and 42.7 lm W-1). They also show a very small efficiency roll-off of about 8.5% from 100 to 1000 cd m-2.
