Synthesis and Characterization of Compounds Containing 1,2,3-Triazole via Click Reaction and Ag(I) Complex

In this work, 1,4-bis(4-phenyl-1,2,3-triazole)benzene, 1,3-bis(4-phenyl-1,2,3-triazole)propane, bis(1-phenyl-1,2,3-triazole)-methylphenylsilane, and 1-ally-4-phenyl-1,2,3-triazole have been designed and synthesized via Click reaction. 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 CHCl3 solutions were observed around ca. 440 nm. And the luminescent coordination compound, namely [AgL1 center dot NO3 center dot 3H(2)O](n), based on the ligand 1-allyl-4-phenyl-1,2,3-triazole has been prepared. In addition, this complex exhibits a 1D 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.
