摘要: Abstract The photophysical properties of three bipolar complexes, Al(PHQ)3 (1), AlQ(PHQ)2 (2), and AlQ2(PHQ) (3) (Q = 8-hydroxyquinoline, PHQ = 5-[(phenothiazine-9′-yl)methyl]-8-hydroxyquinoline) were studied by UV–vis absorption fluorescent spectra. results showed that both energy transfer electron from phenothiazine (Ptz) group to Alq3-center had taken place in the photoluminescence (PL) process Al-complex. Forster non-radiative theory together with spectra applied investigate these Al-complexes. Additionally, thermodynamic analysis validated possibility photo-induce (PET) process. To further confirm PET process, Cu2+ ion was used oxidize aromatic amine observe variation emission Al(PHQ)3. Moreover, dynamics also dynamic fluorescence, some constants obtained.
