“…In detail, for the TPyP solution, two broad-emission bands were recorded at approximately 655 and 711 nm, designated for the Q(0,0) and Q(0,1) bands of the porphyrins [41]. For the Ru(bpy)2Cl2 complex, the fluorescent emission appeared at approximately 609 and 650 nm, attributed to the characteristic emissions from the MLCT excited state [42,43]. The relative intensity of two peaks was to some degree dependent on the excited wavelength and solvents.…”

“…[9][10][11][12][13][14][15][16] Compostos de coordenação apresentam grande potencial para aplicações em sistemas fotoquímicos [17][18][19][20][21][22][23][24][25][26] devido à possibilidade de incorporar diferentes ligantes a centros metálicos para formar subunidades com funcionalidades específicas que podem estar relacionadas às suas transições eletrônicas. 27 Em complexos octaédricos podem ocorrer transições eletrônicas centradas no metal (MC, Metal Centered); Intraligante (IL, IntraLigand); transições de transferência de carga do ligante para o metal (LMCT, Ligand-to-Metal Charge Transfer); e transições de transferência de carga do metal para o ligante (MLCT, Metal-to-Ligand Charge Transfer), Figura 1. O processo fotoquímico, que se inicia com a absorção de luz por uma espécie química e resulta na transição de um elétron do estado fundamental para um estado excitado, pode ter seu mecanismo representado por um diagrama de Jablonski, Figura 2.…”
