Matteson homologation with sodium azide in DMF proved to be an excellent highly stereoselective tool for the synthesis of complex α‐azido and α‐amino acids. Both enantiomers are easily accessible via the choice of the chiral boronic ester auxiliary.

Molecular cages that contain silicon are highly versatile and stable materials with great potential for various scientific and technological applications due to their ability to form stable three‐dimensional frameworks. The synthesis of 2,2,3,3,5,5,6,6,7,7,8,8‐dodecamethyl‐2,3,5,6,7,8‐hexasilabicyclo[2.2.2]octane has already been reported and its modifications at the CH moiety have been demonstrated to afford varied functionality. Here, we present the synthesis and characterization of 2,2,3,3‐tetraphenyl‐5,5,6,6,7,7,8,8‐octamethyl‐2,3,5,6,7,8‐hexasilabicyclo[2.2.2]octane, which is a phenyl‐substituted analogue of such a silicon‐containing cage. The Ph‐substituted Si‐containing cage exhibits a low‐lying LUMO due to the hyper‐conjugation including Si–Si, Si–C σ*‐orbitals, and π(phenyl)‐orbitals, which results in a remarkable bathochromic shift in the UV‐vis absorption spectrum.

A new MOF, named UoC‐11 (UoC = University of Cologne, [Mg4(3F‐BTB)2(OAc)2(DMF)6] · DMF), based on a fluorinated BTB (4,4′,4″‐benzene‐1,3,5‐triyl‐tris‐(benzoate)) derivative and Mg cations was synthesized incorporating additional acetate anions. Its crystal structure was determined from single crystal X‐ray diffraction data (P21/c, Z = 4). It consists of one‐dimensional Mg‐SBUs (strands), interconnected perpendicularly by tritopic linkers forming a dense two‐fold interpenetrating 3D network. Thus, only very small voids are formed which are fully occupied by the solvent. After activation at 150 °C (24 hours), no meaningful N2 adsorption was observed. Compared to the Ca and Sr analogues UoC‐9, UoC‐11 does not exhibit a crystal sponge behaviour. Thermal analysis (TGA) shows a release of all solvent molecules up to ~280 °C and the decomposition of the framework starts above 300 °C.
以氟化 BTB(4,4′,4″-苯-1,3,5-三基-(苯甲酸酯))衍生物和镁阳离子为基础,结合额外的醋酸阴离子,合成了一种新的 MOF,命名为 UoC-11(UoC = 科隆大学,[Mg4(3F-BTB)2(OAc)2(DMF)6] - DMF)。根据单晶 X 射线衍射数据(P21/c,Z = 4)确定了其晶体结构。它由一维 Mg-SBU(链)组成,通过三位连接体垂直相互连接,形成一个致密的两层相互渗透的三维网络。因此,只有很小的空隙被溶剂完全占据。在 150 °C 下活化(24 小时)后,没有观察到明显的 N2 吸附现象。与钙和锶类似物 UoC-9 相比,UoC-11 没有表现出晶体海绵的行为。热分析(TGA)显示,所有溶剂分子在约 280 ° C 的温度下都会释放出来,框架在 300 ° C 以上开始分解。

Materials with tunable properties are often in the focus of materials science. Up to this point four different semiconducting materials and substitution variants have been found that are capable of switching between p‐ and n‐type conduction by a simple change in temperature. In this review, we illustrate previous findings of these pnp‐switching materials and current developments in functional implementations. While in the past decade, the scientific focus was primarily on discovering new materials that possess this intriguing switching effect, recently the first devices were successfully constructed and tested. Using the compounds, Ag18Cu3Te11Cl3 and AgCuS, that exhibit the pnp‐switching behaviour at approximately room temperature and 364 K, respectively, two single‐material diodes were developed and characterized. The approach for inducing this effect is denoted and the fundamental principles for realizing these devices are summarized.

Ruthenium‐catalyzed hydrosilylation of aldehydes with hydrooligosilanes is reported. Among the examined ruthenium catalysts, RuH2(CO)(PPh3)3 gave the best results. The reactions proceed with the Si–Si bonds preserved to afford the corresponding alkoxyoligosilanes in good yields. A series of aryl aldehydes with an electron‐withdrawing group is applicable, whereas those with an electron‐donating group are not suitable for the reaction. Mechanistic considerations suggest that the key points for the preservation of the Si–Si bonds are the formation of zero‐valent ruthenium species and the efficient coordination of the aldehyde to the ruthenium center prior to the oxidative addition of the Si–H bond.

Hygroscopic single crystals of a new hexagonal high‐temperature modification of Sr[ReO4]2 were prepared from a melt of Sr[ReO4]2 ⋅ H2O and SrCl2 ⋅ 6 H2O. The structure analysis of the obtained crystals by X‐ray diffraction revealed that the title compound crystallizes in the ThCd[MoO4]3‐type structure with the hexagonal space group P63/m and the lattice parameters a=1023.81(7) pm and c=646.92(4) pm (c/a=0.632) for Z=2 in its quenchable high‐temperature form. Two crystallographically independent Sr2+ cations are coordinated by oxygen atoms forming either octahedra or tricapped trigonal prisms, whereas the Re7+ cations are found in the centers of discrete tetrahedral meta‐perrhenate units [ReO4]−. Temperature‐dependent in‐situ PXRD studies of dry powder samples of Sr[ReO4]2 exhibited its thermal dimorphy with a phase‐transition temperature at 500–550 °C from literature‐known m‐Sr[ReO4]2 into the newly discovered h‐Sr[ReO4]2 (hexagonal).

Based on the mixed ligands of 1,4‐bis(2,4,6‐tricarboxylpyrid‐5‐yl)benzene (H6BTPB) and 1,4‐bis(imidazol‐1‐yl)benzene (bib), a new cadmium(II) coordination polymer with the molecular formula of {[Cd(bib)(μ2‐H2O)(H2O)2](H4BTPB)0.5(bib)0.5}n (CdCP) was constructed under solvothermal condition, and displayed a 3D supramolecular structure expanded by the hydrogen bonds between the 1D [Cd(bib)(μ2‐H2O)(H2O)2]n ladder chain and the guests. Profiting from its superior stability and inherent luminescence, the prepared CdCP dispalyed great potential as a highly sensitive and selective luminescent sensor in trace detection of 3‐NT biomarker in both water and real bodily fluids through the luminescence quenching effects, with the Ksv and LODs being 2.408×105 M‐1 and 30.3 nM in water, 2.230×105 M‐1 and 44.7 nM in diluted urine, 2.249×105 M‐1 and 43.9 nM in diluted serum, respectively. Subsequent mechanism studies indicated the synergistic effect of internal filtering effect, photo‐induced electron transfer, and fluorescence resonance energy transfer determining the luminescence quenching response of CdCP towards 3‐NT biomarker.
