“…The de-colorization process was pursued by spectrophotometric titration, revealing a consumption of mainly four equivalent protons from HCl at λ max = 625. This outcome agrees with the protonation nature of the tetradentate ligand to furnish the protonated ligand [14][15][16][17][18][19][20][21][22][23][24][25][26] and the hydrated copper salt (CuBr 2 ) (Figure 7b).…”

“…A broad band at λ max = 232 along with two maximum absorptions at 329 and 404 were displayed by the ligand, these electronic transitions could be assigned to n-σ*, π-π* and n-π*; the last electronic absorption designates the formation of the ligand through the condensation process, (Figure 4c). On the other hand, complex 2 exhibited two electronic transitions, a strong band with two shoulders at 240 and 265 nm, which were assigned to n-σ*, while the second wide peak at λ max = 370 nm could be resonated to ligand-to-metal charge transfer (LMCT), Figure 4d [23]. Hence, the coordination of the tetradentate ligand to copper metal center is well designated by this spectral pattern.…”
