[en] In this project we have studied molecular assembly processes of ligands tested in this research group and Pd (II) and Pt (II) metal centers together with recognition processes using as host molecules difunctionalized naphthalenes. The compounds prepared were characterized by nuclear magnetic resonance. First the synthesis and assembly of a ligand is studied. This ligand is derived from the N-monoalkyl-4, 4'-bipyridine with a complex of Pd(II) which has a square planar shape, in deuterated water at room temperature to yield 7a metallocycle. Then, is performed the preparation of inclusion complexes where the metallocycle 7a acts as receptor molecule π-deficient features and naphthalene compounds as guest molecules with difunctionalized π-over features. A study about the stoichiometry of the host-receptor of two inclusion complexes formed and carried out was done and also the calculation of the association constant one of those complexes through spectrophotometrically techniques by UV-VIS. The characterization of the ligand synthesized, the metallocycle, and the inclusion complexes is carried out by nuclear magnetic resonance techniques. Likewise metallocycle 7b is prepared by the assembly of the derived ligand from N-monoalkyl-4, 4'-bipyridine with a complex of Pt(II) in deuterated water but in this case at high temperatures in a microwave oven, characterized by nuclear magnetic resonance. Secondly studied synthesis by two different routes, purification and assembly of a ligand derived from the N-monoalkyl transetilen-4, 4'-bipyridine with a complex of Pd(II).

[gl] Neste proxecto de fin de grado estudáronse procesos de autoensamblaxe molecular con ligandos ensaiados neste grupo de investigación e centros metálicos de Pd(II) e Pt(II) xunto con procesos de recoñecemento molecular empregando como moléculas hóspede naftalenos difuncionalizados. Os compostos sintetizados caracterizáronse por resonancia magnética nuclear. Primeiro estúdase a síntese e ensamblaxe de un ligando derivado da N-monoalquil-4,4'-bipiridina con un complexo de Pd(II) de xeometría planocadrada en auga deuterada a temperatura ambiente para dar lugar ao metalociclo 7a. A continuación, lévase a cabo a preparación de complexos de inclusión nos que o metalociclo 7a actúa como molécula receptora con características π-deficientes e compostos de naftaleno difuncionalizados como moléculas hóspede con características π-excedentes. Realízase un estudo a cerca da estequiometría do sistema hóspede-receptor de dous dos complexos de inclusión formados e lévase a cabo o cálculo da constante de asociación nun de ditos complexos mediante medidas de radiación UV-VIS. A caracterización do ligando sintetizado, do metalociclo e os complexos de inclusión realízase mediante técnicas de resonancia magnética nuclear. Prepárase así mesmo o metalociclo 7b mediante ensamblaxe do ligando con un complexo de Pt(II) en auga deuterada pero neste caso a elevadas temperaturas nun forno microondas e caracterízase por resonancia magnética nuclear. En segundo lugar estúdase a preparación mediante dúas rutas distintas , a purificación e ensamblaxe de un ligando derivado da N-monoalquil-transetilen-4,4'-bipiridina con un complexo de Pd(II).
