1. {"_":"Carbazole-Functionalized Dipicolinato Ln Complexes Show Two-Photon Excitation and Viscosity-Sensitive Metal-Centered Emission.","sup":["III"]}
1. {"_":"咔唑功能化的吡啶二羧酸镧系配合物展现出双光子激发和粘度敏感的中心金属发射。","sup":["III"]}PMID:日期:2022-02-04Eu and Yb complexes with the carbazole-dipicolinato ligand dpaCbz, namely K[Eu(dpaCbz)] and K[Yb(dpaCbz)], were isolated. The Eu complex displayed metal-centred emission upon one-photon excitation with a sensitized emission efficiency of 1.8±0.3 %, corresponding to an intrinsic emission efficiency of 46% and a sensitization efficiency of 3.9%, with an emission lifetime of the emissive state τ of 1.087±0.005 ms. The Yb complex displayed of 0.010±0.001 %, and a τ of 2.32±0.06 μs. The Eu-centred emission was sensitized as well upon two-photon excitation and a two-photon absorption cross-section σ of 63 GM at 750 nm was determined for the complex. The one- or two-photon sensitized emission intensity of the Eu complex changes by more than two-fold when the solvent viscosity is varied in the range 0.5 - 200 cP and the emission is independent of dissolved oxygen. The Yb complex displays a change in emission intensity as well. However, in this case, a dependence of the emission intensity on dissolved oxygen content was observed.

2. Lanthanide nitrato complexes bridged by the bis-tridentate ligand 2,3,5,6-tetra(2-pyridyl)pyrazine: Syntheses, crystal structures, Hirshfeld surface analyses, luminescence properties, DFT calculations, and magnetic behavior.
2. 双三齿配体2,3,5,6-四(2-吡啶基)吡嗪桥联的镧系硝酸盐配合物:合成、晶体结构、Hirshfeld表面分析、发光性质、DFT计算及磁行为PMID:日期:2020-12-15Six dinuclear lanthanide(III) nitrato complexes [Ln(NO)(HO)](-tppz) (where tppz = 2,3,5,6-tetra(2-pyridyl) pyrazine and Ln(III) = Nd (), Sm (), Eu (), Gd (), Tb (), and Dy ()) with bis-tridentate N-heterocyclic 2,3,5,6-tetra(2-pyridyl)pyrazine as bridging ligand have been solvothermally synthesized and characterized via elemental analysis, infrared spectroscopy, thermogravimetric analysis, single-crystal X-ray diffraction, and powder X-ray diffraction. The 3-D Hirshfeld surface and 2-D fingerprint plots show that the main interactions in - are the O⋯H/H⋯O intermolecular interactions with relative contributions of about 62%. Although the poor lanthanide(III)-centered luminescence properties clearly point to the efficiency of nonradiative quenching processes (presence of water molecules in the coordination sphere of the lanthanide(III) ions), the ligand tppz is better suited to sensitize the lanthanide(III)'s emissions of Eu and Nd than Sm, Tb, and Dy. Finally, the magnetic data of Dy comple× reveals antiferromagnetic coupling between Dy ions.

3. Effect of Quencher, Denaturants, Temperature and pH on the Fluorescent Properties of BSA Protected Gold Nanoclusters.
3. 猝灭剂、变性剂、温度和pH对BSA保护的金纳米簇荧光性质的影响PMID:日期:2015-12-01In this paper, we have synthesized BSA protected gold nanoclusters (BSA Au nanocluster) and studied the effect of quencher, protein denaturant, pH and temperature on the fluorescence properties of the tryptophan molecule of the BSA Au nanocluster and native BSA. We have also studied their effect on the peak emission of BSA Au nanoclusters (650 nm). The phtophysical characterization of a newly developed fluorophore in different environments is absolutely necessary to futher develop their biomedical and analytical applications. It was observed from our experiments that the tryptophan in BSA Au nanoclusters is better shielded from the polar environment. Tryptophan in native BSA showed a red shift in its peak emission wavelength position. Tryptophan is a highly polarity sensitive dye and a minimal change in its microenvironment can be easily observed in its photophysical properties.

4. {"_":"Synthesis and Luminescence Properties of Transparent Nanocrystalline GdF:Tb Glass-Ceramic Scintillator.","sub":["3"]}
PMID:日期:2014-03-01Transparent glass-ceramic containing rare-earth doped halide nanocrystals exhibits enhanced luminescence performance. In this study, a glass-ceramic with Tb doped gadolinium fluoride nanocrystals embedded in an aluminosilicate glass matrix is investigated for X-ray imaging applications. The nanocrystalline glass-ceramic scintillator was prepared by a melt-quench method followed by an anneal. The GdF:Tb nanocrystals precipitated within the oxide glass matrix during the processing and their luminescence and scintillation properties were investigated. In this nanocomposite scintillator system, the incorporation of high atomic number Gd compound into the glass matrix increases the X-ray stopping power of the glass scintillator, and effective energy transfer between Gd and Tb ions in the nanocrystals enhances the scintillation efficiency.

5. Synthesis and spectroscopic-electrochemical properties of novel ratiometric Hg (II) chemosensor containing Bodipy and the N-phenylaza-15-crown-5 moiety.
PMID:日期:2013-04-01The aryl-amine containing azacrown ether ring and alkyl-chloro boradiazaindacene (Bodipy) were synthesized by Schiff base condensation. The absorption and emission of a novel Schiff base derivative (based on azacrown-Bodipy ) were performed in presence of different cations such as Zn, Ga, Pb, Hg, NH Ca, Cu, Na, Ni, Cd and Cr. The complexation property of the Schiff base was studied in dimethylformamide (DMF) by interacting azacrown-ether group and transition metal nitrates-ammonium chloride. The electrochemical behavior of the Schiff base has also been investigated by cyclic voltammetry. All experimental results indicated that the new compound act as a selective ratiometric chemosensor for Hg.

6. Optical and electrical properties of electrochemically doped organic field effect transistors.
PMID:日期:2013-02Mixed ionic/electronic conduction in conducting polymers introduces new physics/chemistry and an additional functionality in organic optoelectronic devices. The incorporation of an ionic species in a conjugated polymer matrix results in the increase in electrical conductivity associated with the electrochemical doping of the material. In recent years polymer light emitting electrochemical cells (LECs) have been demonstrated. In such electrochemical optoelectronic devices, mobile ions facilitate the efficient injection of electronic charge carriers creating "" doping regions near the electrodes and lead to efficient electroluminescence light emission. Here, we introduce the same concept of an LEC in the organic field effect transistors (OFETs). The presence of both electronic and ionic charge carriers in the active layers of OFETs brings high charge carrier mobility and light emission even using symmetric source and drain metal electrodes.

7. A CRITICAL STUDY ON THE INTERACTIONS OF HESPERITIN WITH HUMAN HEMOGLOBIN: FLUORESCENCE SPECTROSCOPIC AND MOLECULAR MODELING APPROACH.
7. 橙皮苷与人血红蛋白相互作用的批判性研究:荧光光谱与分子模拟方法PMID:日期:2012-05-01Hesperitin, a ubiquitous bioactive flavonoid abundant in citrus fruits is known to possess antioxidant, anti-carcinogenic, hypolipidemic, vasoprotective and other important therapeutic properties. Here we have explored the interactions of hesperitin with normal human hemoglobin (HbA), using steady state and time resolved fluorescence spectroscopy, far UV circular dicroism (CD) spectroscopy, combined with molecular modeling computations. Specific interaction of the flavonoid with HbA is confirmed from flavonoid-induced static quenching which is evident from steady state fluorescence as well as lifetime data. Both temperature dependent fluorescence measurements and molecular docking studies reveal that apart from hydrogen bonding and van der Waals interactions, electrostatic interactions also play crucial role in hesperitin-HbA interactions. Furthermore, electrostatic surface potential calculations indicate that the hesperitin binding site in HbA is intensely positive due to the presence of several lysine and histidine residues.

8. Self-quenching of uranin: Instrument response function for color sensitive photo-detectors.
PMID:日期:2010-12-01Concentration is a key determining factor in the fluorescence properties of organic fluorophores. We studied self-quenching of disodium fluorescein (uranin) fluorescence in polyvinyl alcohol (PVA) thin films. The concentration dependent changes in brightness and anisotropy were followed by a lifetime decrease. We found that at a concentration of 0.54 M, the lifetime decreases to 7 ps. At a concentration of 0.18 M the lifetime was 10 ps with the relatively high quantum yield of 0.002. In these conditions the fluorescence intensity decay was homogeneous (well approximated by a single lifetime). We realized that such a sample was an ideal fluorescence lifetime standard for spectroscopy and microscopy, and therefore characterized instrument response functions for a time-domain technique. We show that self-quenched uranin enables measurements free of the color effect, making it a superior choice for a lifetime reference over scattered light.

9. Quantitative differentiation of dyes with overlapping one-photon spectra by femtosecond pulse shaping.
9. 利用飞秒脉冲整形技术对具有重叠单光子光谱的染料进行定量区分PMID:日期:2010-01-01We demonstrate that DiI and Rhodamine B, which are not easily distinguishable to one-photon measurements, can be differentiated and in fact quantified in mixture via tailored two-photon excitation pulses found by a genetic algorithm (GA). A nearly three-fold difference in the ratio of two-photon fluorescence of the two dyes is achieved, without a drop in signal of the favored fluorophore. Implementing an acousto-optic interferometer, we were able to prove that the mechanism of discrimination is second-harmonic tuning by the phase-shaped pulses to the relative maxima and minima of these cross-sections.

10. Site-to-site distance distribution in flexible molecules: theoretical evaluation of the donor and/or acceptor fluorescence decay function.
10. 柔性分子中位点间距离分布:供体和/或受体荧光衰减函数的理论评估PMID:日期:2004-10-18We present the theoretical expression describing dependence of the fluorescence intensity decays on the distance distribution ()between energy donors and acceptors in flexible bichromophoric molecules. The expression allows for multiexponential fluorescence decay of the donor- and acceptor-only molecules and takes into account the possibility of incomplete labeling of the molecules by acceptors. It is assumed that the donors and acceptors are static in space and do not move relative to each other during the excited-state lifetime. The potential application of the obtained expression is evaluation of the parameters of the function ().
