  Organized chromophores in layered inorganic matrices

  摘要：

  Recent studies on the intercalation of azoic and xanthenic dyes and of donor-acceptor couples into the interlayer region of hydrotalcite-like compounds (HTlc) will be reviewed. In particular, the synthetic strategy followed to optimize the intercalation of chromophores, together with the chemical, photophysical and photochemical characterization of the obtained materials are presented. The use of HTlc containing easily exchangeable counter-ions allowed to introduce in the interlayer region, anionic chromophores with large size and different shape; moreover, materials with tunable optical properties (emission spectra and lifetimes) have been obtained by the accurate control of synthetic procedures. The confinement of chromophores into the interlayer nanometer-space affords the control of the distance between the guest species and hence of their interactions. Confocal microscopy has been used to investigate the distribution of the fluorescent guests into the microcrystals and the host-guest interactions. Furthermore, the preparation and the fluorescence properties of new intercalation compounds formed between HTlc and xylenol orange anions and between 4-phenylazobenzoate and HTlc, in the presence and absence of an electric field, are reported and discussed with the aim to furnish a wider overview of the potentiality of this emerging class of hybrid materials.

  钠离子电池用偶氮化合物的可逆氧化还原化学

  摘要：

  使用可再生有机电极的可持续钠离子电池（SSIB）是用于大规模可再生能源存储的锂离子电池的有前途的替代品。但是，缺乏高性能阳极材料阻碍了SSIBs的发展。本文中，我们报道了一种基于偶氮基的新型有机阳极材料，用于SSIBs。以偶氮苯-4,4'-二羧酸钠盐为模型研究偶氮化合物的电化学行为和反应机理。它在0.2C下的可逆容量为170 mAh g -1。当电流密度增加到20C时，可逆容量为98 mAh g -1可以保留2000次循环，显示出出色的循环稳定性和高倍率性能。详细的表征表明，偶氮基团是电化学活性位点，可逆地与Na +结合。偶氮化合物和Na离子之间的可逆氧化还原化学性质为开发长寿命和高速率SSIB提供了机会。

• A novel one-pot approach towards dynamically cross-linked hydrogels

  Herein, we report the synthesis of sliding-ring (SR) hydrogel networks in a one-pot click-mediated approach using α,ω-dialkyne poly(ethylene glycol) (PEG) and azido-functionalised cyclodextrin, which acts as both sliding cross-link and end-capping agent. This novel approach resulted in polymeric networks that possess a combination of both SR and covalent (CV) cross-link points. The extent of inclusion complexation and the ratio of SR to CV cross-links in the hydrogels was found to be dependent on both the concentration of the precursors and the curing temperature. Based upon model studies where rotaxanes were synthesised from the same precursors, it was observed that an increase in the precursor concentration led to an increase in click efficiency and inclusion ratio, which in turn affects the overall hydrogel rigidity and elasticity. Hydrogels synthesised at higher curing temperatures led to more homogeneous networks that were significantly tougher as a result of the overall increase in cross-linking density and the extent of CV cross-links. We therefore present a facile one-pot method for the synthesis of SR networks with tunable physicochemical properties. Additionally, the resultant hydrogel networks are potentially capable of supporting post-modification with various (bio)molecules or therapeutics utilizing the remaining azide groups on the cyclodextrin cross-links. Preliminary cytotoxicity studies revealed that the hydrogels did not impede cell growth and demonstrate negligible toxicity. Thus, these networks may have potential for soft-tissue engineering or biomedical applications, including sustained release and drug-delivery systems.

  在本文中，我们报告了利用α,ω-二炔聚乙二醇（PEG）和叠氮功能化环糊精（它既是滑动交联剂，又是端封剂），通过一锅点击介导法合成滑动环（SR）水凝胶网络的情况。这种新方法产生的聚合物网络同时具有 SR 交联点和共价（CV）交联点。研究发现，水凝胶中的包合物复合程度以及 SR 交联与 CV 交联的比例取决于前体的浓度和固化温度。根据用相同前体合成轮烷的模型研究，可以发现前体浓度的增加会导致点击效率和包合比的增加，进而影响水凝胶的整体刚性和弹性。在较高的固化温度下合成的水凝胶可形成更均匀的网络，由于交联密度和 CV 交联程度的整体提高，网络的韧性明显增强。因此，我们提出了一种简便的一锅法，用于合成具有可调理化特性的 SR 网络。此外，利用环糊精交联物上残留的叠氮基团，所生成的水凝胶网络还可能支持各种（生物）分子或疗法的后修饰。初步的细胞毒性研究表明，水凝胶不会阻碍细胞生长，其毒性可忽略不计。因此，这些网络可能具有软组织工程或生物医学应用的潜力，包括缓释和给药系统。
