摘要：
Herein, an extremely simple l-alanine-assisted pyrolysis method was proposed for the construction of a novel hierarchically porous hybrid of Fe(4)N-Fe supported on N-doped carbon nanobelts and Ketjen black carbon (denoted as Fe(4)N-Fe@N-C/N-KB). It has been found that the participation of l-alanine in pyrolysis can dramatically increase the total pyridinic-N/graphitic-N content in Fe(4)N-Fe@N-C/N-KB, which is peculiarly conducive to the enhancement of ORR performance. The in-site formation of the Fe(4)N-Fe heterojunction via the thermal reduction and decomposition of Fe(3)N as well as the introduction of cheap KB can significantly improve the ORR performance. As a result, the activity, durability, and methanol tolerance of this hybrid are comprehensively better than those of commercial 20 wt % Pt/C, promising future applications in practical devices. Density functional theory calculations disclose that the highly improved ORR activity of Fe(4)N-Fe@N-C/N-KB also benefits from the favorable electron penetration and excellent electronic conductivity between the Fe(4)N nanoparticles and the N-incorporated carbon frameworks.

Crystal data: triclinic， space group P1， with a = 13.5251（5）， b = 13.9453（5）， c = 15.3582（5） ?， α = 76.922（3）o， β = 79.740（3）o， γ = 64.248（4）o， V = 2530.83（18） ?3， Dc = 1.496 g/cm3， Z = 1， μ（MoKα） = 1.305 mm-1， F（000） = 1156， the final R = 0.0340 and wR = 0.0638. The Eu（III） ion is coordinated by eight atoms to give a distorted square antiprism coordination geometry. The complex exhibits antiferromagnetism in the temperature range of 300～2 K， and two intense fluorescence emission bands arising from the transitions of Eu3+: 5D0 → 7F1 （595 nm） and 5D0 → 7F2 （618 nm）， respectively. In addition， the fluorescence sensing properties of the complex in CrO42- solution were studied.

摘要：
Fourteen new organotin(IV) complexes were successfully synthesized and characterized by elemental analyses, Fourier transform infrared spectroscopy (FT-IR), multinuclear (1H, 13C, and 119Sn) NMR spectroscopy, high-resolution mass spectrometry (HRMS), and X-ray single-crystal techniques. Crystallographic data showed that the complexes 1b, 2b, 3b, and 5b were macrocyclic compounds, 4b exhibited a one-dimensional spiral chain structure with distorted trigonal bipyramidal geometry, other complexes were centrosymmetric dimers, and there was an Sn2O2 four-membered ring in the middle of the molecule. In-vitro anticancer activity against the three human tumor cell lines NCI-H460, MCF-7, and HepG2 was studied, and the dibutyltin complex 5a is a more potent antitumor agent than other complexes and cisplatin. Cell apoptosis study of 5a with the highest activity on HepG2 cancer cell lines was done by flow cytometry; it was shown that the antitumor activity of 5a was related to apoptosis, and it inhibited proliferation by blocking cells in the G2/M phase. The single-cell gel electrophoresis assay results show that 5a induces DNA damage. 5a interacts with ct-DNA by intercalating the mode of interaction. UV–visible absorption spectrometry, fluorescence competitive, viscosity measurements, and gel electrophoresis results also support the intercalative mode of interaction for 5a with DNA.
Fourteen organotin(IV) complexes were synthesized by one-pot microwave irradiation. The complex 5a exhibited high activity and selectivity for inhibiting the HepG2 cell line. And it causes DNA damage and induces cell cycle arrest at G2/M phase and apoptosis.

摘要：
In this work, we report a tetranuclear Co-4 cluster, namely [Co-4(L)(2)(mu(2)-OCH3)(2)(mu(3)-OCH3)(2)(CH3OH)(2)]center dot 2CH(3)OH (1, H2L = 2-{[(2-hydroxy-3-methoxyphenyl)methylidene]amino}benzoic acid). The complex was synthesized and characterized by IR, elemental analysis, thermogravimetric analysis and single crystal X-ray diffraction. X-ray crystallography reveals that complex belongs to the monoclinic crystal system, space group P2(1)/n. Further, their fluorescence and magnetic properties are also discussed. The variable temperature magnetic susceptibilities for complex indicate the existence of antiferromagnetic exchange interactions.

摘要：
Nitric oxide (NO), an essential biological messenger molecule, participates in various physiological and pathological processes. The sensitive and specific detection of NO is of great significance for understanding the biological function of NO. Here, we synthesized a fluorescent probe (Rho-NO) for highly selective detection of NO both in vitro and in vivo. The high selectivity of Rho-NO is attributed to the fact that NO is easily replaced by electron donor amino group to form N-nitrosation products, causing rhodamine spiro ring open and fluorescence emit. Rho-NO showed a good linear response to NO (0-100 mu M) with a low detection limit (0.06 mu M). Importantly, it exhibited excellent specificity for NO detection in human serum and was also applied for imaging NO in living cells and inflammatory model of zebrafish. This work proves the potential of Rho-NO in pathological research and disease diagnosis. (C) 2021 Elsevier B.V. All rights reserved.

The crystal of complex II is of triclinic system, space group P-(1) over bar with a = 9.9960(4), b = 11.2466(4), c = 14.0509(5) angstrom, alpha = 69.4190(10)degrees, beta = 70.0600(10)degrees, gamma = 81.8090(10)degrees, Z = 1, V = 1389.69(9) angstrom(3), D-c = 1.380 Mg.m(-3), mu(MoK alpha) = 0.950 mm(-1), F(000) = 592, R = 0.0284 and wR = 0.0690.

摘要：
Schiff base pyridine zinc（II） complexes 1～4 have been synthesized via the reaction of the salicylaldehyde-o-aminophenol Schiff base with appended donor functionality， zinc acetate and pyridine. The complexes have been characterized by IR， 1H NMR spectra， elemental analysis and the crystal structures have been determined by X-ray diffraction. Structure analysis results show that they have the same coordination mode and similar steric structure. Complexes 1 and 3 form a one-dimensional chain structure and two-dimensional network structure through the action of abundant hydrogen bonds， respectively. Thermogravimetric analysis shows complexes 1 ～ 4 can exist stably below 150 ℃. The interaction between complexes and ct-DNA were studied by EB fluorescent probe. The result shows that the interaction of the complexes with ct-DNA was intercalation， and the insertion effect of complex 1 is the strongest. It is speculated that the steric hindrance of complex 1 is relatively small， and the aromatic ring on the ligand is more likely to inserted into the base pair of DNA.
