So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Abdullahi, Shittu; Aydarous, Abdulkadir; Salah, Numan researched the compound: Aluminum triquinolin-8-olate( cas:2085-33-8 ).Safety of Aluminum triquinolin-8-olate.They published the article 《Effects of X-ray irradiation on the structural and optical properties of microcrystalline Alq3 powder and its potential dosimetry application》 about this compound( cas:2085-33-8 ) in Radiation Physics and Chemistry.

Tris-(8-hydroxyquinoline) aluminum (Alq3) is a well-known organometallic compound due to its numerous applications in electronic devices including organic light-emitting diodes, photodiodes, and optoelectronics. It has unique optical properties; however, the effect of ionizing radiation on its properties has not been investigated to date. In this study, Alq3 microrods were pressed into small pellets, annealed at 150°C for 1 h and then exposed to X-ray radiation at different doses in the range of 5-20 Gy. Subsequently, their structural and optical properties were analyzed by X-ray diffraction (XRD), Raman spectroscopy, Fourier transform IR (FTIR) spectroscopy, and photoluminescence (PL) emission spectroscopy. XRD results showed a slight shift in the positions of the Alq3 peaks, with no significant change in the crystallinity or phase of Alq3, whereas the intensity of the Raman and FTIR peaks of these pellets systematically decreased upon irradiation The intensity of the PL band of Alq3 at 510 nm initially increased to about three times higher than the unirradiated PL signal under 10 Gy irradiation and then started to decrease. The observed decreases in the intensities of the Raman and FTIR peaks are attributed to the slow/gentle degradation of Alq3, particularly to the breakage of its C-H, C-O, and Al-O bonds. In addition, the linear dose response of Raman and FTIR signals present a nearly excellent dose dependence with a minimal percentage error of 1% and 4%, resp. These results might serve as a basis for the further investigation of Alq3 microrods as a radiation dosimeter. In particular, the observed systematic modifications in the optical properties of Alq3 and the resulting excellent linear response curves of irradiation doses verses signal intensities are quite encouraging.
