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. © 2012 Copyright Taylor and Francis Group, LLC.
