1. Highly efficient room-temperature phosphorescence and afterglow luminescence from common organic fluorophores in 2D hybrid perovskites

Chem. Sci., 2018, Advance Article

DOI: 10.1039/C8SC03563F

Scientists at Fujian Normal University have created novel room temperature phosphorescence materials based on organic/inorganic hybrid perovskites where fluorophores such as 1,8-naphthalimide are doped into the organic layers of the perovskites. They find that the quantum yield of one of the materials is the highest value of reported yellow RTP in air. The strategy presented in the article can be applied to the design of other highly efficient RTP materials and these perovskites could find applications in security ink and white and afterglow LEDs.

2. Highly effective photoreduction of CO₂ to CO promoted by integration of CdS with molecular redox catalysts through metal–organic frameworks

Chem. Sci., 2018, Advance Article

DOI: 10.1039/C8SC02809E

Researchers in China present the first study to integrate inorganic semiconductors and molecular redox catalysts through metal organic frameworks (MOFs). They find that their CdS/UiO-bpy/Co composites are excellent catalysts for the photoreduction of CO₂ to CO under visible light with a CO evolution rate of 235 μmol g^-1 h^-1 and anticipate that the present implantation strategy to make these composites could help design future photocatalysts for CO₂ reduction.

1. A boron imidazolate framework with mechanochromic and electrocatalytic properties

Mater. Horiz., 2018, Advance Article

DOI: 10.1039/C8MH00859K

The design and synthesis of new boron imidazolate frameworks (BIFs) is presented, which is a special subclass of metal–organic frameworks (MOFs). The resulting materials show mechanochromic behaviour and excellent activity and stability for the electrocatalytic oxygen evolution reaction (OER). In contrast to the widely reported MOF-derived electrocatalysts, this work demonstrates that functional MOFs can directly serve as excellent electrocatalysts, providing higher densities of active sites.

本文介绍了新型硼咪唑酯框架（BIFs）的设计和合成，它是金属有机框架（MOFs）的一个特殊子类。所合成的材料显示出了力致变色行为和电催化析氧反应（OER）的优异活性和稳定性。与广泛报道的MOF衍生的电催化剂相比，这项工作证明了功能性MOF材料可直接作为优良的电催化剂，提供更高密度的活性位点。

2. Liquid catalysts: an innovative solution to 2D materials in CVD processes

Mater. Horiz., 2018, Advance Article

DOI: 10.1039/C8MH01088A

Chemical vapor deposition (CVD) has been widely used in the growth of 2D materials owing to its controllability, scalability and low-cost features. In CVD processes, catalysts play a critical role and solid catalysts have long been used, but surface defects usually result in compromise of the quality of the resulting materials. In light of the limitations, liquid catalysts are proving to be extremely effective in improving the quality and enlarging the scale of as-grown 2D materials because of their ultra-smooth and fluent surface. This review discusses the development of liquid catalysts in growing 2D materials by the CVD method and their unique features and advantages over solid catalysts are highlighted.

化学气相沉积（CVD）由于其可控性、可扩展性和低成本等特征而被广泛用于2D材料的生长。在CVD工艺中，催化剂起着关键作用，因此固体催化剂也在长期使用，但是其表面缺陷通常会影响所合成材料的质量。鉴于这些限制，液体催化剂由于其超光滑和流畅的表面，在提升所制备的2D材料的质量和扩大规模方面非常有效。本篇综述讨论了通过CVD方法生长2D材料中液体催化剂的发展，并强调了它们与固体催化剂相比的独特特征和优势。

3. Electrochemically in situ controllable assembly of hierarchically-ordered and integrated inorganic–carbon hybrids for efficient hydrogen evolution

Mater. Horiz., 2018, Advance Article

DOI: 10.1039/C8MH00773J

Inorganic–carbon hybrid materials are an emerging class of nanostructured catalysts that can enhance various energy-oriented electrochemical reactions. Although various methods have been reported, it is still very challenging to controllably generate the hybrid carbon architecture and its inorganic components with a single approach. In this study the authors develop a redox-unit cooperative assembly strategy to make a range of hierarchically-ordered and integrated inorganic–carbon hybrids. The electrochemical behavior can be improved by optimizing the redox states of the polymer precursor, resulting in high activities and stabilities in the hydrogen evolution reaction. This synthesis strategy opens a new way to prepare advanced hybrid materials for energy related electrochemical devices such as for water splitting, fuel cells and lithium batteries.

无机-碳杂化材料是一类新兴的纳米结构催化剂，可以促进各种能源领域的电化学反应。尽管已经报道了多种方法，但是用单一方法可控地生成杂化碳结构及其无机组分仍然是非常具有挑战性的。在这项研究中，作者开发了一种氧化还原单元协同组装策略，制造了一系列多级有序且集成的无机-碳杂化物。通过优化聚合物前体的氧化还原态，可以改善其电化学行为，从而在析氢反应中表现出高活性和稳定性。这种合成策略为制备用于能源领域电化学装置的先进杂化材料开辟了一种新方法，例如水分解、燃料电池和锂电池。

1. Photo-driven morphological transformations of supramolecular polymers actuated by an overcrowded alkene switch

Polym. Chem., 2018, 9, 4808-4812

DOI: 10.1039/C8PY01070F

Authors synthesised an alkene photoswitch functionalized with two rigid 2-ureido-4-pyrimidinone groups, which exhibited reversible and controllable cis/trans isomerisation with UV light/heat. In chloroform, due to the strong intermolecular hydrogen bonds and pi-pi stacking interactions, the trans isomers formed well-defined nanospheres from the linear supramolecular polymers. The cis isomers, which did not have strong intermolecular interactions, formed worm like polymers. The authors then exposed the nanospheres to UV radiation, converting the isomers from trans to cis. This broke the nanosphere structure to form the smaller worm-like polymers. Addition of a hydrogen-bond competing monomer caused further depolymerisation of the system.

本文作者们合成了一种由两个刚性2-脲基-4-嘧啶酮基团官能化的烯烃光开关，在紫外光/热条件下表现出了可逆且可控的顺/反异构化。在氯仿中，由于存在强的分子间氢键和π-π堆积相互作用，反式异构体由线性超分子聚合物形成轮廓分明的纳米球。顺式异构体由于没有强的分子间相互作用，则会形成蠕虫状聚合物。作者们将纳米球暴露在紫外线辐射下，使异构体由反式转化为顺式，导致纳米球结构被破坏，形成了较小的蠕虫状聚合物。在其中加入氢键竞争单体，会引发系统的进一步解聚。

Biomaterials Science (IF: 5.831)

1. Facile dynamic one-step modular assembly based on boronic acid-diol for construction of a micellar drug delivery system

Biomater. Sci., 2018, 6, 2605-2618

DOI: 10.1039/ C8BM00712H

Authors report the spontaneous one-step assembly of a drug encapsulated polymer micelle (Dox/PNAE-M). The system was made using derivatives of dopamine and phenylboronic acid, by varing the ratio of the constituents they were able to make micelles with a maximum Dox loading of 22.4%. The authors then carried out in vitro studies and demonstrated that the system dissembled successfully within acid endo/lysosomes, thereby releasing Dox in a targeted manner. They then tested the Dox/PBAE-M micelles in vivo demonstrating improved anticancer treatment without side effects.

作者们报道了一种包含药物的聚合物胶束（Dox / PNAE-M）的自发性一步组装。该体系由多巴胺和苯硼酸的衍生物制成，通过改变组分的比例，所得的胶束最大Dox载量为22.4％。接着作者们进行了体外研究，证明该体系在酸性内溶酶体中可以成功分解，从而靶向性地释放出Dox。对Dox/PBAE-M胶束进行的体内测试证明了该体系能改善抗癌疗效同时还没有副作用。
