Recent developments in the polymerization of elemental sulfur, inverse vulcanization and functional Chalcogenide Hybrid Inorganic/Organic Polymers (CHIPs) are reviewed.
ABSTRACT High sulfur content copolymers were prepared via the inverse vulcanization of elemental with styrene. This reaction was carried out at a relatively low temperature and invokes new chain transfer mechanism abstraction benzylic protons to form stable copolymers. The use styrene as comonomer for attractive due cost wide spread industrial styrenics in free radical processes. used active cathode material Li‐S batteries that exhibited outstanding device performance, maintaining 489 mAh/g...
We report on the preparation of ultrahigh refractive index polymers via inverse vulcanization elemental sulfur, selenium, and 1,3-diisopropenylbenzene for use as novel transmissive materials mid-infrared (IR) imaging applications. Poly(sulfur-random-selenium-random-(1,3-diisopropenylbenzene)) (poly(S-r-Se-r-DIB) terpolymer from this process exhibit highest any synthetic polymer (n > 2.0) excellent IR transparency, which can be directly tuned by composition. Sulfur or selenium containing...
The accelerator effect of amine activators N-methylimidazole and 4-vinylaniline (4-VA) on inverse vulcanization dynamic covalent polymerization (DCP) has been investigated. sulfur polymer with self-activation comonomer 4-VA could also be used for low temperature DCP to incorporate some volatile monomers. Those approaches provide a new synthetic rate accelerated processes activate S8 copolymerization functional comonomers at lower temperatures under broader range reaction conditions. Please...
A series of novel ortho-terphenylene viologen derivatives (o-TPV2+) with through-space conjugation (TSC) via the combination skeletons structure is reported. Their optoelectronic properties can be adjusted by N-arylation or N-alkylation reactions. Compared other derivatives, o-TPV2+ not only exhibits strong photoluminescence but also retards charge recombination process and stabilizes diradical state without forming a quinoid due to special TSC effect. Based on their redox characteristics,...
Metal–organic framework (MOF)-modified biochars (BC) have gained recognition as potent adsorbents for phosphate. However, essential insights into the electronic interfacial state of MOFs remain lacking. In this study, we propose a novel topological transformation strategy to directionally regulate states BC/MOFs composites. The optimized exhibited an excellent selective phosphate adsorption capacity 188.68 mg·g–1, coupled with rapid sorption kinetics 6.81 mg·(g·min0.5)−1 in simulated P-laden...

This paper presents a co-design control scheme that integrates Distributed Model Predictive Control with dynamic quantizers for networked nonlinear continuous systems operating under limited communication bandwidth. Each subsystem-based formulation considers the quantizer's influence within optimization problem in proposed method. Both quantizer parameters and law are optimized simultaneously real time, which offers potential improvements performance of closed-loop system certain limitation....

A highly diastereo- and enantioselective asymmetric allylic alkylation reaction with respect to prochiral 3-substituted benzofuran-2(3H)-ones MBH carbonate by a chiral biscinchona alkaloid catalyst was investigated. The corresponding adducts, containing quaternary center at the C3-position of benzofuran-2(3H)-one as well vicinal tertiary center, were generally obtained in high yields (up 97%) very good 98:2 dr) enantioselectivities 95% ee).
The current work reports an organocatalytic strategy for the asymmetric catalysis of chiral benzofuran-2(3H)-ones bearing 3-position all-carbon quaternary stereocenters.

Although naphthalene diimide (NDI) and its derivatives have been widely used for organic Li-ion batteries (OLIBs), they are limited by a low lithium uptake capacity ambiguous lithiation mechanism. Herein, we report two isometric thionated-NDI cathodes (cis-2S trans-2S) obtained replacing O with S in the imide groups which improves battery performance compared parent NDI (P-NDI). Remarkably, position of atoms plays an important role as potential plateau cis-2S was 100 mV higher than trans-2S,...
