Figure 7. (A) Ring structures of {PAnPO₂Eu(hfac)₃}₂ with vibrational modes; (B) normalized concentration-dependent luminescence (λ_ex = 350 nm); (C) normalized temperature-dependent emission (λ_ex = 350 nm) in CH₂Cl₂ (1.5 × 10^-5 M); (D) normalized emission spectra of {PAnPO₂Tb(hfac)₃}₂ (λ_ex = 330 nm) in CH₂Cl₂ (1.5 × 10^-5 M, black) and solid state (red) under room temperature.
