Abstract ：
Three pargyline-phosphine copper(I) clusters, [Cu-4(C equivalent to C-C9H12N)(3)(PPh3)(4)](PF6) (1) and [Cu-6(CC-C9H12N)(4)(dppy)(4)](X)(2) (dppy = diphenyl-2-pyridylphosphine; X = PF6 for 2 and X = ClO4 for 3), were synthesized. Their structures were fully characterized using various spectroscopic methods and X-ray crystallography, which showed that the stoichiometry and nature of pargyline and phosphine ligands play an important role in tuning the structure and photophysical features of Cu(i) clusters. Interestingly, clusters 1, 2 and 3 exhibited red, orange and yellow phosphorescence with high quantum yields of 88.5%, 22.0% and 40.2%, respectively, at room temperature. Moreover, clusters 1-3 show distinct temperature-dependent emissions. The excellent luminescence performance of 1 and 3 was designed and employed for the construction of monochrome and white light-emitting devices (LEDs).

Abstract ：
X-ray photoelectron spectroscopy (XPS) and near-edge X-ray absorption fine structure (NEXAFS) spectra, as well as the ground-state electronic/geometrical structures of the unparalleled non-classical (NC) isomer C-1-C-68(NC3) and the chlorinated derivative C-1-C-68(NC3)Cl-28 with its partially hydrolyzed derivatives C-1-C-68(NC3)Cl-26(OH)(2) and C-1-C-68(NC3)Cl-25(OH)(3), along with the classical non-IPR (isolated pentagon rule) fullerene C-2v-C-#6073(68) and its metal carbide clusterfullerene Sc2C2@C-2-C-#6073(68) have been calculated at the density-functional-theory (DFT) level. The electronic structures and X-ray spectra of classical and non-classical fullerenes are undoubtedly distinguished from their counterparts, as are the substances that have undergone chlorination. The two derivatives produced in the partial hydrolysis of chloride C-1-C-68(NC3)Cl-28 also exhibit distinctive properties. The "fingerprint" in X-ray spectroscopy is capable of offering an effective tool for the identification of the aforementioned isomers, as evidenced by the reality that the XPS and NEXAFS spectra demonstrate isomer dependence. Ultraviolet-visible (UV-vis) absorption spectroscopy of Sc2C2@C-2-C-#6073(68) was carried out using time-dependent (TD) DFT calculations. The emulated results and the outcomes of the experiment coincide well. This study indicates how X-ray and UV-vis spectroscopy methods can provide valuable data to support researchers in exploring the electronic structure of fullerene materials and the identification of isomers in both further experimental and theoretical disciplines.

Abstract ：
Sulfur-doped graphdiyne at different sites has a tremendous impact on its electronic structure and properties. Due to the large number of S-doping sites, there is no comprehensive and systematic experimental and theoretical study regarding the identification of S-doped graphdiyne configurations. In this paper, X-ray photoelectron (XPS) and near-edge X-ray absorption fine structure (NEXAFS) spectra as well as geometries of 10 sulfur-doped graphdiyne molecules have been simulated at the density functional theory (DFT) level. Different types of carbon spectra were theoretically modeled to analyze the contribution of the spectra. Calculated results show that the NEXAFS spectra exhibit a clear dependence on the local structure. The theoretically simulated XPS spectra are in good agreement with the experimental spectra. The XPS spectra combined with the NEXAFS spectra can provide effective information for identifying the 10 S-doped conformations. Our research results provide further theoretical prediction and guidance for the experimental synthesis of S-doped graphdiyne, which solves the difficult problem of identification of S-doped carbon-based materials.

Abstract ：
X-ray photoelectron spectroscopy (XPS) and nearedge X-ray absorption fine structure (NEXAFS) spectra, as well as the ground-state electronic/geometrical structures of the newly discovered two non-classical isomers C-2-C-76(NC2) and C1- C-76(NC3) with their derivatives C-2-C-76(NC2)(CF3)(14) and C-1- C-76(NC3)Cl-24, as well as the non-IPR(isolated pentagon rule) isomer C1-C-#17418(76) with its embedded metal fullerene U@ C-1-C-#17418(76) have been calculated at the density functional theory (DFT) level. The electronic structure after chlorination is significantly different in the simulated X-ray spectrum. Both XPS and NEXAFS spectra reflect obvious isomer dependence, indicating that the "fingerprint" in X-ray spectroscopy can provide an effective means for the identification of the above-mentioned fullerene isomers. Time-dependent DFT was used to simulate the ultraviolet-visible absorption spectrum of U@C-1-C-#17418(76). The calculated results are in good agreement with the experimental consequence. This work reveals that theoretically simulated X-ray and UV-vis spectroscopy techniques can provide valuable information to help researchers explore the electronic structure of fullerenes and the identification of isomers in future experimental and theoretical fields.

Abstract ：
Due to their specific spinel structure, ternary oxides with multi-catalytic sites on a highly active exposed surface are recommended as alternative bio-catalysts. Spinel zinc vanadate with two-dimensional nanosheets (Zn3V3O8 NSs) was synthesised using a one-step hydrothermal route with CTAB and glycine as a bi-surfactant, where each NS has a thin thickness (25 nm) and wide cross section (2 mu m). As a key parameter for peroxidase-like activity, the Michaelis-Menten constant (K-m) for Zn3V3O8 NSs was calculated to be 0.271 mM with TMB and 1.317 mM with H2O2 at optimum conditions, indicating a higher affinity for the exposed (011) facet towards horseradish peroxidases. This affinity is related to the geometric matching between V4+ active sites and the terminal amino groups of TMB. The V4+ ions on the (011) facet act as dangling bonds and readily react with H2O2 in a Fenton-like reaction. The peroxidase-like activity for Zn3V3O8 NSs is verified by the formation of [V(IV)-OO] by the O-2(-) and V5+ near V4+ sites, but oxidase activity for Zn3V3O8 NSs. Based on the peroxidase-like activity, Zn3V3O8 NSs were used as a colorimetric glucose sensor with a wide linear range from 0.01 to 0.5 mM and a detection limit (LOD = 3 sigma/S) of 2.81 x 10(-7) M. The colorimetric sensor also exhibited high accuracy and selectivity in synthetic perspiration samples.

Abstract ：
X-ray photoelectron and near-edge X-ray absorption fine structure (NEXAFS) spectra, as well as the ground-state electronic/geometrical structures of a newly discovered nonclassical isomer C-2v-C-66(NC), and two classical fullerene isomers C2-#4466C66 and C-s-C-#4169(66) with their hydrogenated derivatives [C-2v-C66H4(NC), C-2-(C66H4)-C-#4466, and C-s-(C66H4)-C-#4169] have been calculated at the density functional theory (DFT) level. Significant differences were observed in the electronic structures and simulated X- ray spectra after hydrogenation. Simultaneously, both X-ray photoelectron and NEXAFS spectra reflected conspicuous isomer dependence, indicating that the "fingerprints" in the X-ray spectra can offer an effective method for identifying the above-mentioned fullerene isomers. The simulated ultravioletvisible (UV-vis) absorption spectroscopy of C-2v-C66H4(NC) has also been generated by means of the time-dependent DFT method, and the calculations are well consistent with the experimental results. Consequently, this work reveals that X-ray and UVvis spectroscopy techniques can provide valuable information to help researchers explore the fullerene electronic structure and isomer identification on the future experimental and theoretical fullerene domains.

Abstract ：
The traditional classical fullerene is only composed of pentagons and hexagons, with many different topologies, of which only a few structures conform to the isolated pentagon rule (IPR), which means all five-membered rings are separated by hexagons, whereas isomers that violate the rule are called non-IPR isomers. In contrast, the non-classical fullerene consists of other kinds of polygons such as squares and heptagons in addition to pentagons and hexagons. X-ray photoelectron spectra (XPS), near-edge X-ray absorption fine structure (NEXAFS) spectra and X-ray emission spectra (XES), as well as the ground-state electronic/geometrical structures of the important non-IPR isomers C-3v-C-#1205(58) and C-2-C-#1078(58), and the remarkable non-classical isomer C-s-C-58(NC) with its two fluorides C-s-C-58(NC)F-18(A) and C-s-C-58(NC)F-18(B), have been computed at the density functional theory (DFT) level. Significant differences in the electronic structures and simulated X-ray spectra have been observed after fluorination. Meanwhile, strong isomer dependence has been shown in these spectra, which means the "fingerprint" in the X-ray spectra can effectively identify the above-mentioned fullerene isomers. As a consequence, the work can provide useful information especially isomer identification for experimental and theoretical research in fullerene science.

Abstract ：
Stimuli-responsive electrically bistable devices are significant for the development of new generation memory materials. In this study, a co-crystal, (MA-H)(2)(PZDC)center dot 4H(2)O (MA = 1,3,5-triazine-2,4,6-triamine, melamine; H-2-PZDC = pyrazine-2,3-dicarboxylate), was firstly fabricated as an active layer to prepare an ITO/(MA-H)(2)(PZDC)center dot 4H(2)O/Ag device, which exhibits switchable conductivity states with an ON/OFF current ratio of 10(5). Interestingly, the electrical bistability performance can be quenched by heating and irradiating stimuli accompanied by reversible crystalline-to-amorphous transformations, which can be recovered by soaking the samples in water. Based on the crystal structures after heating/irradiation and theoretical calculations, a photo/thermal responsive electrical bistability switching mechanism was proposed: the decreased band gap caused by the disappearance of lattice water around PZDC(2-) will inhibit the formation of a countering space-charge field and consequently, the electrical bistability behaviors will vanish. This study paves a new way for the design of stimuli-responsive electrical bistability materials.

X-ray photoelectron spectra (XPS), near-edge X-ray absorption fine structure spectra (NEXAFS), and X-ray emission spectroscopy (XES), as well as the ground-state electronic/geometrical structures about the significant classical isolated-pentagon rule (IPR) isomer D-3h-C-#24109(78), the non-IPR isomers C-2-C-#22010(78) and C-1-C-#23863(78), and the nonclassical isomer C-2-C-78(NC2) with its chlorinated derivative C-2-C-78(NC2)Cl-24, which are newly obtained in the experiment, have been calculated at the density functional theory (DFT) level. Significant differences have been observed in the electronic structure and the X-ray spectra. All X-ray spectra have shown strong isomer dependence; consequently, the "fingerprint" in X-ray spectra shows a very effective way to isolate the fullerene isomers above. As a result, this work indicates that X-ray spectroscopy can provide valuable identification for classical and nonclassical fullerenes as well as their derivatives on experimental and theoretical studies.
