Untangling interactions of a zinc(II) complex containing a coumarin-porphyrin unit with alkaloids in water solutions: a photophysical study.
نویسندگان
چکیده
A metal complex 1 derivative from a coumarin bearing a porphyrin unit was spectroscopically characterized and its sensing ability towards the alkaloids caffeine 2, nicotine 3 and cotinine 4 was evaluated in these studies. This probe shows to be sensitive to the alkaloids studied, where a detectable amount of 2.5 ± 0.3 μM of cotinine was determined in dam water from the Vigia Dam located in the Montoito village region, Alentejo district, Portugal. The interaction of 1 with cotinine was also verified by MALDI-TOF-MS, where it was found with peaks at 877.2 and 1053.3 m/z corresponding to the species [1H](+) and [1CotinineH](+), respectively.

The zinc(II) complex [Zn2(dmdtc)2(μ-dmdtc)2] has been synthesized directly from thiram ligand, containing a disulfide bond {dmdtc = N,N-dimethyldithiocarbamate; thiram = N,N-tetramethylthiuram disulfide}, and characterized by elemental analysis and spectroscopic methods. Surprisingly thiram, undergoes a reductive disulfide bond scission upon reaction with Zn2+ in methanolic media to give the [Z...
