Formation of thin luminescent Eu 3 þ -LB films by in situ coordination with 2,3,5,6-tetra(2 0 -pyridyl)pyrazine and 1-octadecanol in pure and mixed Langmuir monolayers
2020Co-Authors: Fernanda P Fugisawa, Ana Paula Ramos, Osvaldo Antonio Serra, Sousa Filho, Maria Elisabete Darbello ZaniquelliAbstract:a b s t r a c t The in situ complexation between 2,3,5,6-tetra(2-pyridyl)pyrazine (tppz) molecules and europium ions at the air-liquid interface by means of mixed 1-octadecanol Langmuir films is reported. These films were transferred to solid supports by means of the Langmuir-Blodgett (LB) technique. The EDS maps attested the homogeneity of the LB films as well as the presence of the europium ions. The mixed alcohol/tppz LB film contained a larger amount of europium ions as compared to the pure octadecanol LB film. This work reports the production of a thin luminescent Eu 3 þ film containing europium ions using only alcohol molecules as ligands-an unexpected result, since it is well known that there is an occurrence of non-radiative deactivation of excited europium by hydroxyl groups. Europium ion multiple binding sites were detected from lifetime decay measurements of these films in the presence of tppz molecules
