Abstract We have synthesized a new aluminium complex, Bis (5-choloro-8-hydroxyquinoline) (2,2’bipyridine) aluminium Al(Bpy)(5-Clq)2 and characterized it for structural, thermal and photoluminescence properties. The prepared material was characterized by Fourier-transformed infra-red spectroscopy (FTIR), thermal gravimetric analysis (TGA) and photoluminescence. The prepared material showed thermal stability up to 370 C. Absorption Spectra of the material was measured by UV-visible spectroscopy. Solution of Al(Bpy)(5-Clq)2 in ethanol showed peak at 393 nm, which may be attributed due to (π– π*) transitions. The photoluminescence spectrum of Al(Bpy)(5-Clq)2 in ethanol solution showed peak at 535 nm. The time resolved photoluminescence spectra of the material showed two life time components. The decay times of the first and second component are 5.3 ns and 21.2 ns respectively. The prepared material emits the light in green region (PL spectra) so it can be used as an emissive layer in organic light emitting diodes.
