] with 3-(2-pyridyl)-5-R-1,2,4-triazoles (R=H, CH3, Ph respectively HL 1, HL 2, HL 3) was proposed based on IR, NMR, UV spectroscopy and MALDI mass spectrometry data analysis. It is found that the complexation of HL 2 and HL 3 with Pd2+ ions results in a decrease of their fluorescence intensity and it is vice versa in case of HL 1. Furthermore, the influence of the substituent (R) in the 3-(2-pirydyl)-5-R-1
具有3-(2-吡啶基)-5-R-1,2,4-三唑的四个新钯配合物[ Pd(HL 2 )Cl 2和Pd(L 1-3)2 ]的结构(R = H,基于IR,NMR,UV光谱和MALDI质谱数据分析,提出了CH 3,Ph分别为HL 1,HL 2,HL 3)。发现HL 2和HL 3与Pd 2+离子的络合导致它们的荧光强度降低,并且在HL 1的情况下反之亦然 。此外,还研究了3-(2-吡啶基)-5-R-1,2,4-三唑中取代基(R)对HL 1-3的荧光和蛋白水解性能的影响。
