One new polymer [Co(L)(H2O)2]n(1) was synthesized by 4-(ethoxycarbonyl)-5-methyl-1H-1,2,3-triazole-1-carboxylic acid(Emtc) under the in situ solvent thermal reaction(H2L = 1-(carboxymethyl)-5-methyl-1H-1,... One new polymer [Co(L)(H2O)2]n(1) was synthesized by 4-(ethoxycarbonyl)-5-methyl-1H-1,2,3-triazole-1-carboxylic acid(Emtc) under the in situ solvent thermal reaction(H2L = 1-(carboxymethyl)-5-methyl-1H-1,2,3-triazole-4-carboxylic acid). The title complex performs a wave-like 2D framework and the ligand H2L demonstrates the coordination mode as μ4-η-2:η-1η-1:η-1. The crystal structure has been established by single-crystal X-ray diffraction, and characterized by FT-IR. Fluorescent property was investigated in this work. Hirshfeld surface analysis has also been carried out on 1, and obvious main intermolecular interactions are observed. 展开更多

Solid surface fluorescence (SSF) spectra of fibrinogen (FG) adsorbed on a glass surface were measured. For comparison, solution fluorescence (SF) spectra of native, thermally denatured, urea denatured FG solution with FG desorbed from a glass surface and the SSF spectra of native FG powder were recorded. To analyze the structural changes induced by the surface adsorption, all the aqueous samples mentioned above were analyzed by circular dichroism (CD) spectroscopy. The results demonstrated that the structural changes of FG induced by glass adsorption caused changes in the spectroscopic features of the SSF spectra, especially in the excitation (EX) spectra. It is suggested that SSF spectroscopy may be a useful tool for studying the structures of surface/interface biomolecules and for evaluating the biocompatibility of biomaterials. 展开更多

The surface enhanced fluorescence effect of acridine orange fluorophore in the proximity of Au nanoparticles has been investigated experimentally in the system of aqueous solution.Significant enhancement of the fluorescence intensity was observed when the system was excited with 532 nm or 442 nm CW lasers.The influence of the distances between neighboring Au particles as well as that between the fluorophore molecules and the Au surface were explored experimentally.The results demonstrated that a compact distribution of metallic particles was able to produce stronger fluorescence enhancement.Proper separation between the fluorophore molecules and the metal surface was favorable for a better enhancement. 展开更多
