title = "Untangling interactions of a zinc(ii) complex containing a coumarin-porphyrin unit with alkaloids in water solutions: A photophysical study",
abstract = "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.",
