Fourier transform infrared spectroscopy(FT-IR) and nuclear magnetic resonance spectroscopy(NMR) were used to confirm the compounds' structures. The effect of silicon atom on the optical properties has also been studied. The UV-vis absorption wavelength of silicon-containing compound is about ca. 10 nm red-shifted when compared with that of other three compounds. The fluorescence emission bands of the compounds in CHCl_3 solutions were observed around ca. 440 nm. And the luminescent coordination compound, namely [AgL1?NO_3?3H_2O]n, based on the ligand 1-allyl-4-phenyl-1,2,3-triazole has been prepared. In addition, this complex exhibits a 1 D chain structure. The crystal structure has been determined by single-crystal X-ray diffraction, and the optical properties have been investigated by fluorescence spectrum. In summary, our work may provide new materials with luminescent property which is potentially useful in material fields.展开更多

The azide-free synthetic approaches provide a powerful and straightforward alternative to the assembly of diverse 1,2,3-triazoles without the use of azides. In this review, we summarize the recent development of the construction of 1,2,3-triazoles under azide-free conditions.展开更多
