In 2019,Polymers (Basel, Switzerland) included an article by Chen, Shuang; Liu, Feng; Wang, Chao; Shen, Jinghui; Wu, Yonggang. Formula: C6H7BO3. The article was titled 《Simple route to synthesize fully conjugated ladder isomer copolymers with carbazole units》. The information in the text is summarized as follows:
Two isomer polymers, P3 and P6, with fully conjugated ladder structures are presented by simple synthetic routes. The well-defined structures of fully conjugated ladder polymers P3 and P6 were ensured by the high yields of every reaction step. The fully rigid ladder structures were confirmed by NMR (NMR), fourier transform IR spectroscopy (FTIR), and photophys. test. Polymers P3 and P6 with bulky alkyl side chains exhibit good solution processability and desirable thermostable properties. After the intramol. cyclization reaction, the band gaps of polymers P3 and P6 become lower (2.86 eV and 2.66 eV, resp.) compared with polymers P1 and P4. This initial study provides insight for the rational design of fully ladder-conjugated isomeric polymers with well-defined structures. In addition to this study using 2-Hydroxyphenylboronic acid, there are many other studies that have used 2-Hydroxyphenylboronic acid(cas: 89466-08-0Formula: C6H7BO3) was used in this study.
2-Hydroxyphenylboronic acid(cas: 89466-08-0) belongs to acyl phenylboronic acid. Phenylboronic acid (PBA) has been used to extract β-blockers (a class of aminoalcohol-containing drugs) from aqueous solution, rat, and human plasma. Formula: C6H7BO3
