Self-assembled tubular nanostructures of tris(8-quinolinolato)gallium(iii)

Abstract

We report for the first time the controllable growth of tubular nanostructures at the nanoscale of the broadly applied organic drug material, tris(8-hydroxyquinoline)gallium (Gaq₃), by an extremely facile approach. The products show a relatively low turn-on field (8.5 V μm⁻¹) and a very high maximum current density (2.3 mA cm⁻²). The length of the Gaq₃ tubes and nanostructures can be readily manipulated and the adopted method is highly transferrable to other organic materials.
