“…More specific techniques may be required to remove trace impurities, such as potentially toxic copper species in ATRP‐ and CuAAC‐derived materials [ 80 ] or residual ruthenium from ROMP‐derived materials, particularly for hydrophilic polymeric components. [ 81 ] Not only short‐term toxicity, but also long‐term immunogenicity can affect biocompatibility, particularly for therapeutic applications. This can be worrisome even for inherently biocompatible substances.…”

Polymeric nano‐ and microscale materials bear significant potential in manifold applications related to biomedicine. This is owed not only to the large chemical diversity of the constituent polymers, but also to the various morphologies these materials can achieve, ranging from simple particles to intricate self‐assembled structures. Modern synthetic polymer chemistry permits the tuning of many physicochemical parameters affecting the behavior of polymeric nano‐ and microscale materials in the biological context. In this Perspective, an overview of the synthetic principles underlying the modern preparation of these materials is provided, aiming to demonstrate how advances in and ingenious implementations of polymer chemistry fuel a range of applications, both present and prospective.

“…Based on the experimental data, logistic and neural network models were used to classify and discuss the different catalyst combinations. The results of Michał Patrzałek et al [2] showed that the water-soluble Ru catalyst could be eliminated by the addition of thiocyanate ions (with or without the support of charcoal additives) after AHOM in pure water. The developed purification method makes the aqueous decomposition method more practical and the used water-soluble catalysts easier to separate from the aqueous decomposition products.P.…”

This paper presents an analysis of ethanol coupling to prepare C4 olefins based on the cubic spline interpolation algorithm. Firstly, the cubic spline interpolation was utilized to fit and plot the trends of temperature, catalyst combination, ethanol conversion rate, and C4 olefin selectivity. Additionally, a polynomial fitting model was established to determine the functional relationships of ethanol conversion rate and C4 olefin selectivity with different catalysts and temperatures, thereby identifying their dependencies on temperature. Subsequently, interpolation fitting was conducted for the variables over time. As the reaction is reversible, a dynamic equilibrium was observed after 273 minutes, allowing for predictive function modeling. Discrepancy analysis between predicted values and experimental data revealed prediction errors of 4.19% and 2.11% for A8 and B7 ethanol conversion rates, and 0.03% and 4.48% for A2 and A3 C4 olefin selectivity, respectively. Combining these errors led to the inference of the catalyst in Appendix II as 200mg1wt%Co/SiO2-200mgHAP with an ethanol concentration of 0.9ml/min.

N,Nʹ‐Diarylimidazolium salts containing haloalkyl functional groups that are reactive with various nucleophiles are considered to be promising reagents for the preparation of functionalized N‐heterocyclic carbene (NHC) ligands, which are in demand in catalysis, materials science, and biomedical research. Recently, 4‐chloromethyl‐functionalized N,N'‐diarylimidazolium salts became readily available via the condensation of N,N'‐diaryl‐2‐methyl‐1,4‐diaza‐1,3‐butadienes with ethyl orthoformate and Me3SiCl, but these compounds were found to have insufficient reactivity in reactions with many nucleophiles. These chloromethyl salts were studied as precursors in the synthesis of bromo‐ and iodomethyl‐functionalized imidazolium salts by halide anion exchange. The 4‐ICH2‐functionalized products were found to be unstable, whereas a series of novel 4‐bromomethyl functionalized N,N'‐diarylimidazolium salts were obtained in good yields. These bromomethyl‐functionalized imidazolium salts were found to be significantly more reactive towards various N, O and S nucleophiles than the chloromethyl counterparts and enabled the preparation of previously inaccessible heteroatom‐functionalized imidazolium salts, some of which were successfully used as NHC proligands in the preparation of Pd/NHC and Au/NHC complexes.
