摘要: Abstract A novel luminescent metal complex, (MQPF) 3 Al 2 , with 8-hydroxyquinoline aluminum and 9,9-diphenylfluorene was synthesized. The optical properties were investigated by UV–vis absorption fluorescence emission spectra. results showed that the luminescence quantum yield of 0.612 in THF it emitted red light band gap 3.18 eV estimated from onset absorption. spectra exhibited obvious solvent effect. With increase polarity solvents changed obviously appeared blue shift about 60 nm at room temperature. In addition, light-emitting can be quenched both electron donor ( N -dimethylaniline) acceptor (Fullerene), where processes followed Stern–Volmer equation. However, when adding 1,4-dicyanobenzene (DCB) which a stronger to solution fluorescent intensity increased.
