  摘要：

  有效地使用杀生物物质需要将活性部分构建到分子背骨中，该分子可以在低压和长时间高温爆轰条件下按需输送和分解。目的是在破坏存储设施及其内容的同时，利用释放出的能量产生的杀菌产品破坏任何残留的有害空气传播剂。精心选择的富含碘的化合物的分解会产生大量非常活泼的杀菌剂，氢碘酸（HI）和碘（I 2）。多碘阴离子，即，我3 -我5 -这类杀菌剂的极好来源，可以通过与大型对称阳离子（如烷基铵盐）的相互作用来稳定。我们已经设计并合成了适合的，具有高达3.33 g cm -3的高密度化合物，它们是具有各种烷基铵阳离子的低压聚碘化物，可输送的碘含量范围为58.0-90.9％。

  通过抑制惰性气氛中的自氧化实现高效锡钙钛矿太阳能电池

  摘要：

  锡钙钛矿太阳能电池（TPSC）不尽人意的功率转换效率（PCE）和长期稳定性限制了其作为铅钙钛矿太阳能电池（LPSC）替代品的进一步发展。大量研究集中在O 2和H 2 O的负面影响上，而关于惰性气氛中的降解机制的讨论仍然不足。在此，首次揭示了锡钙钛矿在氮气气氛中的光诱导自氧化，并证明了弹性晶格畸变是快速降解的关键作用。光子的连续注入诱导能量从激发的 A 位阳离子转移到振动的 Sn-I 框架，导致钙钛矿晶格的弹性变形。因此，过度扭曲的 Sn-I 骨架释放出游离碘，并以分子碘的形式进一步氧化 Sn 2+ 。通过适当设计的光暗循环测试，基于(Cs 0.025 (MA 0.25 FA 0.75 ) 0.975 ) 0.98 EDA 0.01 SnI 3太阳能电池实现了14.41%的显着PCE，这是迄今为止混合三重TPSC的记录。研究结果揭示了自氧化是 TPSC 在惰性气氛中降解的关键，并提出了增强锡钙钛矿晶格以获得高效、稳定

However, by the addition of hydrochloric acid to the synthetic solution, 2D [(ED)2PbI4]Cl2 crystals are interestingly constructed without substitution of iodides by chlorides. The importance of chloride ions in the structure has been revealed by employing the single-crystal X-ray diffraction technique. Isolated chlorides, through

  在这项工作中，我们证明了使用乙二铵（ED）作为氢碘酸中的有机阳离子合成了包含面共享PbI 6 4-八面体的一维EDPbI 4晶体。然而，通过向合成溶液中添加盐酸，有趣地构建了2D [（ED）2 PbI 4 ] Cl 2晶体，而没有碘化物被氯化物取代。通过采用单晶X射线衍射技术已经揭示了氯离子在结构中的重要性。通过与铵基团形成氢键并生成（ED）2 Cl 2 2+来分离氯离子模板层，减少了有机阳离子和无机单元之间的相互作用，因此导致形成几乎未变形的PbI 4 2-钙钛矿层。对于EDPbI 4和[（ED）2 PbI 4 ] Cl 2，所得晶体的带隙分别确定为2.72 eV和2.30 eV 。热重分析（TGA）和差示扫描量热法（DSC）测量表明，两种化合物在高达250°C的温度下均具有热稳定性，而没有任何相变。

  solution allows the partial substitution of MA in MAPbI3 by H3NCH2CH2NH3 (H2en). Surprisingly, there is 1:1 exchange of the monovalent cation MA by the dication H2en. The charge compensation results from a deficit of Pb2+, leading to a series MA1−2y(H2en)2yPb1−yI3 with 0≤y≤0.25. This model has been supported by single‐crystal measurements and NMR investigations. The substitution results in a continuous

• A new layered nano hybrid perovskite film with enhanced resistance to moisture-induced degradation
  作者：Wenlong Jiang、Jifei Ying、Wei Zhou、Kongchao Shen、Xing Liu、Xingyu Gao、Fuqiang Guo、Yanmin Gao、Tieying Yang

  In this paper, a new layered hybrid perovskite film ((EDA)(MA)(2)[Pb3I10]) was synthesized through one-step method. Ethylenediamine (EDA) cation was introduced into the perovskite lattice to synthesize a layered structure with improved resistance to degradation by humidity. The effects of humidity and time on crystal structure, composition, morphology and absorption spectra of (EDA)(MA)(2)[Pb3I10] were analyzed by in situ grazing incidence X-ray diffraction (GIXRD), scanning electron microscope (SEM), and UV-Vis spectroscope. The results reveal that a (EDA)(MA)(2)[Pb3I10] film is more moisture resistant than a CH3NH3PbI3 film which is widely used in the perovskite solar cell now. UV-Vis spectroscopy result also shows that the layered structure film is a suitable solar absorber with a bandgap (1.67 eV), which is close to the optimum value for solar photoelectric conversion. Compared to CH3NH3PbI3, the low-cost perovslcite structure offers greater tunability on a molecular level for further material optimization and possibility for widely used in the future.
