  Prudent Choice of Iron‐Based Metal‐Organic Networks for Solvent‐Free CO ₂ Fixation at Ambient Pressure

  摘要：

  AbstractThe rising global warming and associated climate change demand efficient tactics to reduce CO2 concentration in the atmosphere. Conversion of epoxides to cyclic carbonates utilizing CO2 is a promising and sustainable approach towards CO2 fixation. However, the inert nature of CO2 and high activation energy requirement for the particular reaction necessitate the use of efficient catalysts. In this work, we have designed and developed a heterogeneous catalyst using catechol functionalized guanidinium based ligands (L1) and Fe(III) ions to perform the CO2 fixation reaction. The resulting amorphous material (Fe−L1) possesses metal‐organic network as revealed through different characterization methods. The optimized catalyst Fe−L1 is efficient for the conversion of a variety of epoxides into their corresponding cyclic carbonates in very good yield (>80 %). The reactions were performed under atmospheric pressure without solvent and external additives (e. g., TBAI or KI). The investigation of the mechanistic pathway indeed validates the synergistic effect of metal and halide ions that leads to the efficient conversion of different epoxides into cyclic carbonates. Furthermore, no significant loss in the catalytic activity of the Fe−L1 is noticed up to six cycles. The post catalytic analyses clearly indicate the robust nature of the catalyst. The developed one component bifunctional catalytic system can pave way towards transition to sustainable carbon capture and conversion.

  自剥离的胍基离子共价有机纳米片 (iCON)

  摘要：

  共价有机纳米片 (CONs) 已成为多功能应用的二维功能材料。尽管层间 π-π 堆积、水解不稳定性、可能的重新堆积阻止了它们从结晶多孔聚合物剥落到少数薄层 CON 上。我们预计通过内在离子接头合理设计结构可能是在没有外部刺激的情况下产生自剥离 CON 的解决方案。为了解决这个问题，我们合成了三种具有抗菌性能的基于离子共价有机纳米片 (iCON) 的自剥离卤化胍。自剥离现象也得到了分子动力学 (MD) 模拟的支持。内在离子胍单元对革兰氏阳性菌和革兰氏阴性菌的自剥脱和抗菌性能都起着关键作用。使用此类 iCON，我们设计了一种混合基质膜，可用于具有合理医疗益处的抗菌涂层。

  self-exfoliated guanidinium halide based ionic covalent organic nanosheets (iCONs) with antimicrobial property. Self-exfoliation phenomenon has been supported by molecular dynamics (MD) simulation as well. Intrinsic ionic guanidinium unit plays the pivotal role for both self-exfoliation and antibacterial property against both Gram-positive and Gram-negative bacteria. Using such iCONs, we have devised a mixed
