] 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
