Xu, Weifeng;Liu, Xiang;Cai, Jianzhe;Xue, Tiemeng;Tang, Kewen research published 《 Synthesis of reusable cyclodextrin polymers for removal of naphthol and naphthylamine from water》, the research content is summarized as follows. As one group of important naphthalene derivatives, naphthol and naphthylamine are diffusely employed as dye intermediates. The presence of naphthol and naphthylamine in water systems may pose risks to the environment and public health due to their carcinogenicity. In this study, four mesoporous polymers prepared by β-cyclodextrin derivatives and tetrafluoroterephthalonitrile were obtained and applied to adsorbing 1-naphthylamine, 2-naphthylamine, 1-naphthol, and 2-naphthol from water. The impact of adsorption time, initial concentration of naphthol and naphthylamine, and temperature on the adsorption efficiency of the four polymers were explored sep. The four polymers present fast adsorption kinetics toward naphthol and naphthylamine, attaining 93 ∼ 100% of adsorption equilibrium uptake for 1-naphthol, 1-naphthylamine, 2-naphthylamine in 15 min, and 87 ∼ 90% of equilibrium uptake for 2-naphthol in 15 min. The kinetics could be depicted well by the pseudo-second-order kinetic model. The adsorption isotherms of the four polymers toward naphthol and naphthylamine accord with the Redlich-Peterson or Sips model. The maximum adsorption capacities of 1-naphthylamine, 2-naphthylamine, 1-naphthol, and 2-naphthol are 189.9 mg/g, 82.8 mg/g, 137.7 mg/g, and 88.7 mg/g, resp. The adsorption ratio increases fast with reducing the initial concentration of naphthol and naphthylamine, and the adsorption ratio of naphthol and naphthylamine in 5 mg/L can achieve over 95% in 25 °C. In addition, the four polymers can be effortlessly regenerated by a gentle and simple washing procedure with little reduction in performance. The adsorption performance of the four polymers toward the four naphthalene derivatives can be improved by increasing the adsorption temperature In conclusion, the prepared β-cyclodextrin polymers exhibit rapid water treatment in removing the four low-concentration naphthalene derivatives with convenient regeneration and good reusability.

Xu, Shuainan;Jin, Yehao;Li, Rui;Shan, Meixia;Zhang, Yatao research published 《 Amidoxime modified polymers of intrinsic microporosity/alginate composite hydrogel beads for efficient adsorption of cationic dyes from aqueous solution》, the research content is summarized as follows. Polymers of intrinsic microporosity (PIM-1) has demonstrated great potential in adsorption and separation fields. In this study, PIM-1 was structured into an applicable and efficient adsorbent using a facile way. PIM-1 was first modified by amidoxime, and then the amidoxime modified PIM-1 (AOPIM-1) was mingled into alginate (Alg) hydrogel to obtain composite hydrogel beads. The AOPIM-1/Alg composite beads were further employed for removal of malachite green (MG) from aqueous solution and the effects of doped ratio, adsorbent dosage, contact time, and initial dye concentration on the MG adsorption performance were systematically investigated. The MG adsorption capacity of pure Alg beads was substantially enhanced after incorporating AOPIM-1. Furthermore, isothermal, kinetic and thermodn. studies were performed to explore the fundamental adsorption behavior. Both Freundlich isotherm and Langmuir isotherm models can fit the adsorption isotherm data well, and the adsorption kinetics is well described by Pseudo-second-order. The adsorption process is feasible, spontaneous and endothermic. In addition, mixed dyes adsorption measurements indicate that AOPIM-1/Alg beads are highly selective to adsorb cationic dyes from anionic/cationic mixed dyes solution The regeneration test shows that above 90% of the adsorption capacity of the composite beads can be maintained after 10 cycles of MG adsorption/desorption. These findings point that AOPIM-1/Alg composite hydrogel beads are an efficient, up-and-coming and recyclable adsorbent for cationic dyes adsorption from aqueous solution

The effective treatment for dengue virus infection continues to be a challenge. The authors herein reported the authors’ continued SAR exploration on the spiropyrazolopyridone scaffold. Introducing different substituents at the 3-́ or 5-́site of the pyrazolopyridone core or moving the benzyl chain to the adjacent nitrogen led to a significant loss of potency on DENV-2. While a narrow range of substitutions were tolerated at the para-position of the Ph ring, di-substitution on the Ph ring is beneficial for DENV-2 potency and has variable influences on DENV-3 potency depending on the exact compound Among these mols., compounds (JMX0376) with 4-chloro-3-fluorobenzyl and (JMX0395) with 2,4-bis(trifluoromethyl)benzyl showed the most potent and broadest inhibitory activities against DENV-1 to -3 with nanomolar to low micromolar EC₅₀ values.

Xiong, Shaohui;Pan, Chunyue;Dai, Guoliu;Liu, Cheng;Tan, Zhijian;Chen, Chuang;Yang, Song;Ruan, Xuehua;Tang, Juntao;Yu, Guipeng research published 《 Interfacial co-weaving of AO-PIM-1 and ZIF-8 in composite membranes for enhanced H₂ purification》, the research content is summarized as follows. Porous asym. composite membranes (ACMs) have attracted intensive attentions in energy-efficient gas separations However, fabricating ACMs with defect-free interface and enhanced selectivity without sacrificing permeability remains great challenge. Herein, a major step towards this goal is proposed by employing an efficient co-weaving strategy to regulate interfacial microstructure of ACMs with bilayer geometry on porous substrates. The double layers are constructed by in-situ growing zeolitic imidazolate frameworks-8 (ZIF-8) on the surface of amidoxime-functionalized polymer of intrinsic microporosity-1 (AO-PIM-1) layer (denoted as AO-PIM-1@ZIF-8). The pre-designed amidoxime groups on the AO-PIM-1 backbone provide abundant coordinate sites for Zn (II) ions, offering advantages for building a continuous membrane. Consequently, the obtained AO-PIM-1@ZIF-8 membrane demonstrates remarkable performance in H₂/CO₂ separations, with the H₂/CO₂ selectivity of 11.97 and the H₂ permeability of up to 5688 Barrer at 298 K and 1 bar. Both the H₂ permeability and H₂/CO₂ selectivity exceed most of reported ACMs. This is contributed either by position-space renormalization for AO-PIM-1 chains or pore space partition in ZIF-8 at the interface. The study reports herein offer an alternative route to develop high-performance composite membranes for improved gas separations
