Preparation of 8-hydroxyquinoline wires by decomposition of tris(8-hydroxyquinoline) aluminium

Abstract

We fabricated 8-hydroxyquinoline (HQ) wires by two methods, decomposition of tris(HQ) aluminium at low pressure in a tube furnace and heating of HQ powder at atmospheric pressure. Fabricated wires were crystalline, and exhibited the same optical properties (absorption and photoluminescence) as HQ powder. While the properties of wires prepared by two different methods were the same, it should be noted that synthesis by decomposition of tris(HQ) aluminium required elimination of mechanical vibration of the growth tube. Implications of decomposition of tris(HQ) aluminium during organic vapour phase deposition growth on organic optoelectronic device performance are discussed.

“…Pristine HNTs represented the characteristic diffraction peaks at 11.79°, 19.83°, and 24.6°with corresponding crystal planes of (001), (100), and (002), respectively [44]. After loading pristine HNTs with 8HQ, the XRD pattern revealed no new peak except one peak at 14.17°, which corresponds to that of 8HQ [45]. However, the peaks represented the shift of ± 0.10 to the right side, demonstrating that some disturbance in the structure of HNTs is seen due to the intercalation of 8HQ into HNTs.…”
