2. Estudos sobre interações da 2,3,5,6-tetra(-piridil)pirazina (tppz) com európio e efeitos na luminescência do complexo Eu(ttfa)3 / Studies on the interactions of 2,3,5,6-tetra(-pyridyl)pyrazine (tppz) with europium and effects on the luminescence of the Eu(ttfa)3 complex.
In this work, we have conducted studies on the interactions of 2,3,5,6-tetra(-pyridyl)pyrazine (tppz) with Eu3+ in different situations. In the first of them, we have made a detailed study on the ongoing interactions in solution between tris(thenoiltrifluoroacetonate)europium(III), Eu(ttfa)3 and tppz, where it was verified that tppz act as a luminescence sup
