Síntese e caracterização de compostos de coordenação formados entre os ligantes phen-dxm e dpqdTzol com íons de metais de transição d6 Fe(II) e Ru(II)

Abstract

Neste estudo foi investigada a espectroscopia molecular de alguns complexos contendo ligantes fenantrolínicos com vistas a aplicação em celas fotovoltaicas, no futuro. Foram sintetizados e caracterizados dois ligantes fenantrolínicos extendidos (phendxm e dpqdtzol) e os seus respectivos complexos contendo Fe(II) e Ru(II). Para comparação foram sintetizados os complexos de Fe(II) e Ru(II) com fenantrolina. Estes compostos foram caracterizados por análise elementar, espectroscopia vibracional, eletrônica, 1H RMN e espectroscopia Raman.

In this study was investigated the molecular spectroscopy of some coordination compounds containing phenanthrolinic ligands for the application in photovoltaic cells, in the future. Two extended phenanthroline ligands (phendxm and dpqdtzol) and their respective coordination compounds containing Fe(II) and Ru(II) were synthesized and characterized. For comparison, the complexed Fe(II) and Ru(II) coordination compounds were synthesized with phenanthroline. These compounds were characterized by elemental analysis, vibrational, electronic spectroscopy, 1H NMR and Raman spectroscopy.
