Abstract ：
Rosin,a renewable and abundant resource,has been extensively processed and chemically modified to endow it with special properties,especially in the surfactant industry.In this study,four rosin-based quaternary ammonium asymmetric gemini surfactants(RGS-2-n)with different alkyl chain lengths(n=12,14,16,18)were synthesized using a simple two-step method based on dehydroabietylamine as the raw material.The feasibility of these surfactants for cleaning purposes was comprehensively evaluated,suggesting that the surfactants own high surface activity and good cleaning performance.Furthermore,by successfully introducing the amine group of dehydroabietylamine into the hydrophilic group of the sur-factants,we avoided its potential harm to the environment and water pollution.Density functional theory proves rosin-based gemini surfactants with asymmetric structure can further improve cleaning efficiency.Overall,our findings suggests that RGS-2-n surfactants are promising and sustainable candidates for cleaning electric plates,and provide new opportunities for rosin application in the electric industry.

Abstract ：
The exploitation of new green polymerization avenues for the effective synthesis of polymers by reversible-deactivation radical polymerization plays a critical role in pursuing the development of polymeric materials. In this work, serials of deep eutectic solvents (DES) with intermolecular-hydrogen-bonding interaction were constructed as catalysts and medium for actuating reversible complexation-mediated polymerization (RCMP) for the first time, yielding methacrylate polymers with high monomer conversion and narrow dispersion molecular weight in both water and oil systems. The mechanism and elementary reaction of RCMP were explored deeply, revealing that the complexation of initiator with DES to generate radicals was a ratecontrolling step and intermolecular-hydrogen-bond was primary factor to influence polymerization rate. Moreover, the insights of density functional theory calculations revealed that negative electrostatic potential ensured nucleophilic capacity. This investigation demonstrated the considerable potential of DES for RCMP, which is anticipated for other polymerization applications as a novel medium mode. © Science China Press 2024.

Abstract ：
Copper -based metal -organic frameworks (Cu-MOFs) are a promising multiphase catalyst for catalyzing C -S coupling reactions by virtue of their diverse structures and functions. However, the unpleasant odor and instability of the organosulfur, as well as the mass -transfer resistance that exists in multiphase catalysis, have often limited the catalytic application of Cu-MOFs in C -S coupling reactions. In this paper, a Cu-MOFs catalyst modi fied by cetyltrimethylammonium bromide (CTAB) was designed to enhance mass transfer by increasing the adsorption of organic substrates using the long alkanes of CTAB. Concurrently, elemental sulfur was used to replace organosulfur to achieve a highly ef ficient and atomeconomical multicomponent C -S coupling reaction.

Abstract ：
As one of the most potent greenhouse gases, SF6 has a significant economic and environmental impact on the purification and recovery of exhaust gases from the semiconductor industry. The adsorption and separation performance of SF6 on a two-dimensional covalent organic framework TAT-COFs-1-AB with different functional groups (-SO3H, -Et, -NH2, -OMe, -OH, -H) was investigated by using grand canonical Monte Carlo (GCMC) simulations and density functional theory (DFT) calculations. The results show that the adsorption at low pressure depends on the interactions between the SF6 and COF frameworks, while at high pressure it is mainly affected by the porosity. The highest adsorption capacity of 8.44 mmol/g (298 K, 100 kPa) is exhibited by TAT-COF-1-AB-H, which has the highest porosity. Chemical functionalization was found to be effective in enhancing the SF6/N-2 selectivity. Among all the functionalized COFs, TAT-COF-1-AB-NH2, with the highest specific surface area and strong heat of adsorption, showed the highest selectivity. The simulation of self-diffusion also shows consistent results with the GCMC simulation. The findings highlight that the adsorption capacity is influenced by substituent and porosity, with SF6 showing a consistent preference for adsorption at hollow sites, as evidenced by binding energy and charge transfer analyses.

Abstract ：
Deep eutectic solvent (DES) is used as both photocatalyst and solvent for photoinduced reversible complexation-mediated polymerization (photo-RCMP), which enables a rapid polymerization to produce polymers with predictable molar mass and low molar mass dispersity (D). This work illustrates a comprehensive understanding of DES-accelerated RCMP's mechanism and kinetic features through quantum chemical calculations and kinetic modeling. According to the results, electrons transferring from hydrogen bond in DES to iodine atom in alkyl iodide (RI) initiator under light irradiation lowers the decomposition free energy of complex RI-DES. This procedure facilitates the generation of primary radicals, thus contributing to the DES-accelerated phenomenon. In the meantime, the reaction paths are identified by computation as (i) decomposition of RI-DES under light irradiation generates active radicals and center dot I-DES complex and (ii) combination of two center dot I-DES releases iodine (I2) and regenerates DES. In addition, kinetic modeling based on the method of moments successfully identifies kinetic features of polymerization in the presence and absence of DES, respectively. Kinetic modeling shows a fast increase in primary radicals concentration and rapid build-up of the photo-RCMP activation-deactivation equilibrium, demonstrating that DES is a beneficial photocatalyst and solvent to enable the rapid generation of primary radicals and accelerate the completion of catalytic cycle. This research provides an in-depth understanding of DES-involved photo-RCMP and lays a theoretical foundation for expanding the application of DES to other polymerization systems.

Abstract ：
Covalent organic frameworks (COFs) constitute a promising research topic for photocatalytic reactions, but the rules and conformational relationships of 1D COFs are poorly defined. Herein, the chain edge structure is designed by precise modulation at the atomic level, and the 1D COFs bonded by C, O, and S elements is directionally prepared for oxygen-tolerant photoinduced electron transfer-atom transfer radical polymerization (PET-ATRP) reactions. It is demonstrated that heteroatom-type chain edge structures (& horbar;O & horbar;, & horbar;S & horbar;) lead to a decrease in intra-plane conjugation, which restricts the effective transport of photogenerated electrons along the direction of the 1D strip. In contrast, the all-carbon type chain edge structure (& horbar;C & horbar;) with higher intra-plane conjugation not only reduces the energy loss of photoexcited electrons but also enhances the carrier density, which exhibits the optimal photopolymerization performance. This work offers valuable guidance in the exploitation of 1D COFs for high photocatalytic performance. This work offers valuable guidance in the exploitation of 1D COFs for high photocatalytic performance. 1D Covalent organic frameworks (COFs) with sql topology matches to non-linear C2 and D2h building blocks are fabricated. All-carbon compared to hybrid-atom-containing chain edge structures can increase carrier density, more effectively mitigate thermal relaxation phenomenon, reduce the energy loss of photoexcited electrons, and realize more effective in-plane transport of photoexcited electrons for enhanced oxygen-tolerant photoinduced electron transfer-atom transfer radical polymerization (PET-ATRP) performance. image

Abstract ：
We introduce an approach in diblock copolymer design, where modifying the junction point with rigid bulky monomer expands the cross-sectional area of the interface and leads to a decrease in the repeat period. Using living anionic polymerization, we synthesized a series of dialkynyl midfunctionalized poly(styrene-b-methyl methacrylate) (PSM-DA) and functionalized them using the thiol-alkyne click reaction with specifically selected rigid bulky monomers: PSS-(3-mercapto)propyl-heptaisobutyl substituted (PSS) and 1-adamantanethiol (ADA). This modification, though involving only a single monomer unit within the diblock copolymer structure, brought about a significant reduction in domain size, with PSS and ADA reducing it by 18% and 15%, respectively. The results indicate a method for reducing the domain sizes of block copolymers, which could lead to advancements in lithography and various nanotechnological applications.

Abstract ：
Removal of hetero ions from the hydrogen peroxide solution is a crucial step in purifying electronic-grade H2O2. Conventional adsorption materials are challenged to meet the need for the simultaneous adsorption of both anions and cations in solvents. UiO-66 (Zr) modified by acetic acid and amino group for simultaneous adsorption of phosphate and Pb2+ in H2O2 purification was fabricated in this work. The as-prepared defective UiO-66-NH2 (Zr) demonstrated a significant increase in specific surface area and porosity, along with more exposed sites for phosphate and Pb2+ adsorption. The adsorption capacity of De-UiO-66-NH2 for phosphate and Pb2+ in H2O2 solution was 52.28 mg g(-1) and 35.4 mg g(-1), which is 1.19 times and 1.88 times that of unmodified UiO-66 (Zr), respectively. The trace simultaneous adsorption with both 100 ppb phosphate and Pb2+ showed removal rates of 94.0% and 88.7%, respectively, confirming the practicality of MOF materials in the purification of electronic chemicals. This work highlights the potential of Zr-based MOFs as anionic and cationic simultaneous adsorbents for highly efficient purification of electronic-grade solvents.

Abstract ：
Despite the wide utility of micellar palladium (Pd) nanoparticle (NP)-catalyzed Mizoroki-Heck reactions in laboratory and industrial synthesis, the easy construction of micellar Pd NPs and the detailed role of surfactants remain the focus of attention. Here, we present a simple and sustainable strategy to construct a nanoreactor by connecting micelles with Pd NPs. This strategy enables us to obtain ultrasmall Pd NPs with an average particle size of 1.8 nm, mainly in situ synthesized by triethylamine (Et3N) reduction and stabilized by chelating with sugar-based surfactant micelles. The first-order kinetic model related to the initial concentration of Pd-based catalyst is established, and the apparent activation energy of this reaction in aqueous micellar solutions is calculated to be 40.49 kJ mol-1. The mechanism of the active species ultrasmall Pd(0) NPs obtained by the reductive elimination of Pd(ii) precursors by base was demonstrated. Notably, the recycled aqueous reaction mixture containing the micelles and Pd NPs can be reused. A simple and sustainable strategy is proposed to construct a nanoreactor by connecting micelles with in-situ prepared ultrasmall Pd NPs to efficiently catalyze the Mizoroki-Heck reaction.
