Complexes of pyridine and 2-ethylpyridine with a series of boron Lewis acids have been studied using ¹H, ¹¹B, and ¹³C NMR. The difference in chem. shifts (Δδ_c-4) between the boron complex and the free pyridine were correlated with calorimetric data. The ¹³C data show that Δδ_c-4 of pyridines provides a measure of the strength of the N → B bond, thus allowing a scale of acidity for boron compounds to be derived.

Zhang, Zixu published the artcileGuanidine-functionalized graphene to improve the antifouling performance of boron acrylate polymer, Formula: C23H20BN, the publication is Progress in Organic Coatings (2021), 106396, database is CAplus.

A series of antifouling composite coatings based on guanidine-functionalized graphene (GNG) and self-polishing boron acrylate polymer (BAP) were prepared Compared to graphene oxide, GNG had more wrinkles on its surface and was more uniformly distributed in the interior and on the surface of BAP, resulting in the tight binding of inorganic and organic compounds at the interface. The BAP/GNG composite coatings exhibited excellent algae anti-adhesion performance. Specifically, the inhibition rate of Phaeodactylum tricornutum reached 99.2%, and high antibacterial rates of up to 94.2% and 95% were obtained for Escherichia coli and Staphylococcus aureus, resp. This performance is ascribed to the polishing of BPA, exposing the guanidine-functionalized graphene on the surface. On one hand, as a filler, the prepared guanidine-functionalized graphene improved the antifouling ability by adjusting the hydrolysis rate of the antifouling coating. On the other hand, the exposure of guanidine-functionalized graphene and the hydrolysis of the polymer matrix enhanced the antifouling capability. BAP/GNG shows promise as an antifouling coating with potential applications in marine antifouling.

Li, Yakun published the artcileAntifouling behavior of self-renewal acrylate boron polymers with pyridine-diphenylborane side chains, Recommanded Product: Triphenyl(pyridin-1-ium-1-yl)borate, the publication is New Journal of Chemistry (2018), 42(24), 19908-19916, database is CAplus.

Currently, most high-performance tributyltin (TBT)-free antifouling paints contain cuprous oxide (Cu₂O) in their formulations, leading to a serious challenge to the marine environment and ecosystem. In this study, non-metal acrylate boron polymers (ABPs) were synthesized using acrylate acid polymers (AAPs) as the backbone and a pyridine-Ph borane compound as the side chain with hydrolyzable functional groups. The antifouling mechanism of ABPs researched by XPS and EDS indicated that the antifouling performance of ABPs was realized by the hydrolysis of hydrophobic di-Ph borane pyridine side groups. The results of diatom anti-setting test showed that fewer or no algae cells were attached on the surfaces of ABPs with higher contents of hydrophobic di-Ph borane pyridine side groups. The growth rates of algae suspension solutions containing ABPs were close to that of the blank solution without ABPs. Antifouling paints made of ABPs showed excellent antifouling performances in the Yellow Sea of China. This study provides new insights into the development of ABPs with desirable antifouling properties and environmental friendliness.

To repel the unwanted fouling organisms, various strategies were developed. During these methods, most static antifouling surfaces can not effectively deter the adhesion of marine biofouling in the long term. In this study, self-healing acrylate boron fluorinated polymer films (SABFPs) with dynamic surfaces were facilely prepared by mixing perfluoropolyether (PFPE) lubricant with acrylate boron fluorinated polymer (ABFP) by ultrasonic dispersion. The self-healing mechanism was investigated by analyzing the film thickness change and the distribution of elements under different conditions. Weight loss measurement demonstrated the self-replenishing lubricant and self-polishing polymer surfaces constitute the dynamic surfaces, which reduce the adhesion of fouling organisms in a significant extent. Moreover, the prepared samples exhibited outstanding abrasion performance. Advantageously, this study provided a simple method for preparing marine antifouling films under environmentally friendly conditions.

We constructed two kinds of amphiphilic acrylate boron fluorinated polymers (ABFPs) with backbones comprising acrylate fluorinated polymers (AFPs) and side chains comprising hydrolyzable pyridine-phenylborane functional groups. We determined the hydrolysis rates of the ABFPs by measuring their weight loss ratios. The ABFPs with shorter fluorinated side chains had higher rates of hydrolysis. We investigated and confirmed the amphiphilic and antifouling behavior of the ABFPs, using XPS and surface wettability analyses. During immersion for 90 days in the Bohai Sea of China, the ABFP coatings exhibited good antifouling performance. We also assessed the environmental characteristics of the ABFP coatings by determining the COD (COD) and growth rate of diatoms on their surfaces. The present study provides new insight into the development of environmentally friendly ABFPs with desirable antifouling properties.

The electrochem. oxidation of R₃B (I; R = Me, Bu, Ph, 1-naphthyl, mesityl) was difficult, and the anodic peak potentials did not reflect the reactivity of I toward O₂. Complexation with NH₃ or pyridine facilitated the electrochem. oxidation of I. Polarog. reduction of I (R = Ph, 1-naphthyl, mesityl) gave the anion radicals, which dimerized at a rate governed by the solvating ability of the solvent.

The electrochem. properties were studied of trimethyl-, tri-n-butyl-, triphenyl-, tri-α-naphthyl-, and trimesitylborons, as well as their complexes with NH₃ and pyridine. Cyclic voltammograms of the oxidation of trimethylboron in a supporting electrolyte of 0.1M NaBF₄ in MeCN at 25° are shown. The electrochem. oxidation of several organoboron compounds and their complexes on a Pt disk electrode by cyclic voltammetry is also shown, using a supporting electrolyte of Bu₄NBF₄ in MeCN. The polarog. reduction of 10^-3M triarylborons and their complexes in 0.1M Et₄NClO₄ is also described. The simplest organoboron compounds are electrochem. oxidized with difficulty, and the value of their half-wave oxidation potentials cannot be used for evaluating their reactivities with respect to O and other chem. oxidizing agents; the formation of complexes with NH₃ and pyridine rarely increases the capability of the organoboron compounds to be electrochem. oxidized.
