摘要: The characteristics of the LB films of Schiff base aluminium(Ⅲ), tris(2-hydroxy-5-nitro N-dodecyl-benzylideneaminato) aluminium (Ⅲ) [Al (TA 12)3], were studied.The surface pres sure-area(r-A) isotherm of Al(TA12)3 in the pure water subphase was investigated.The molec ular area, 0.48 nm2, is one-third of the expected value that indicates the formation of an aggre gate.The Langmuir-Blodgett (LB) films of Al(TA12)3 were transferred and characterized.The UV-Vis spectra and the AFM image both confirmed that the J-aggregates formed.The polarized UV-Vis spectra indicated that the complex plane had to be oriented with an angle of about 30° to the substrate surface.The IR spectra suggested that the complexation took place between aluminium ions and the oxygen atoms of the ligand rather than the nitrogen atom.
