Investigation on Structural Characteristics of Tris-(8-hydroxyquinoline) Aluminum

LI Hai-rong, ZHANG Fu-jia, ZHENG Dai-shun (School of Physics, Lanzhou University, Lanzhou 730000, China)  
An comprehensive understanding of the characteristics of the organic material tris-(8-hydroxyquinoline) aluminum (Alq 3) is meaningful for organic light-emitting devices (OLEDs). Thin films of Alq 3 are among the most efficient electroluminescent molecular films known to date. Alq 3 samples were synthesized and purified. The purity of samples is up to 98.5%. The electronic and crystallographic structure of Alq 3 has been studied. The results of a joint experimental investigation based on a combination of X-ray diffraction (XRD) spectrum, hydrogen nuclear magnetic resonance (NMR) spectrum, infrared absorption (IRA) spectrum, mass (MS) spectrum, X-ray emission (XRE) spectrum and fluorescence spectrum of Alq 3 have been investigated. The analysis on NMR spectrum of Alq 3 shows that the coordinate interaction between Al 3+ and O ion is more intensive than that between Al 3+ and N ion. Al 3+ hasn't replaced H ion that suggests the Al-O bond is covalent but not ionic bond in Alq 3 molecule. There are still H + around O ion. Since there are six coordination bonds around Al 3+, O and N ions are both have strong binding force with Al 3+. Therefore Alq 3 has two types of geometrical isomers, namely mer isomer and fac isomer. From the IRA spectrum of the Alq 3, the broad characteristic peak at 3 417cm -1 corresponding to OH - stretching vibration confirmed that the Al-O are coordinate not ionic bond. The prominent peaks which is the characteristic of the absorption vibration of the aromatic ring skeleton at 1 588, 1 550, 1 467 and 1 400cm -1 suggests that the conjugate action of aromatic rings in molecule is very strong and all electron orbit of quinolinic rings are π bonding hybridizations. The disagreement between IRA spectrum of Alq 3 and HQ is excellent for indicating that there is a strong coordinate action which affect O bonding heavily between Al 3+ and O ions. From the MS spectrum the ratio of charge/mass of Alq 3 has been achieved. We prospect if a further cleavage occurred, a peaks of Alq + after losing a ligand from Alq + 2 should locate at m/e=171. However, the peak was not observed indicating that the state of Alq + is difficult to exist. The IRE data shows that the K α1,2 peaks have shifted comparing to Al due to the perturbation as the ligand gives to 2p electron of Al. The perturbation is related to coordination intensity. The shift of K β of Alq 3 mainly resulted from the chemical environment variation around Al atomics. It also relate to binding intensity and coordination number. The intensity of K β is lower than that of K α The wave length of K β is shorter than that of K α.The peak of K β shifted to lower energy (about 3.5eV) whereas the peak of K α1,2 shifted to higher energy (0.3 and 1.6eV) comparing to Al. Surprisingly, a weak adjoint peak at 1 537.5eV was observed. We ascribed it to the formation of the hybridization orbit among O 2s, O 2p, N 2s, N 2p and Al 3p orbits. Fluorescence data confirmed the existence of a fluorescent species formed between Al ion and 8-hydroxyquinolinol.
