Growth and characterization of tris(8-hydroxyquinoline)-aluminum molecular films

Re-condensation and decomposition of Tris(8-hydroxyquinoline)-aluminum in a vapor transport ampoule

“…This finding is in agreement with a recent report [15]. Thus, the T sub -dependence of the physical properties of the Alq 3 films deposited at T sub ffi 90-120 1C [14] was not due to the isomeric transformation but could be attributed to the steric effect that the higher thermal energy (for T sub Z120 1C) allowing an adjustment of correct orientation among these complex Alq 3 molecules to form a crystalline phase leads to a change in the activation energy for the adhesion process [16,23,24]. Similar behavior about this steric effect was also observed during the deposition of small organic molecular films of C 60 [22] and Cu-phthalocyanine [23].…”

“…However, due to the complexity that Alq 3 molecule has two geometrical isomers, meridional (mer-Alq 3 ) and facial (fac-Alq 3 ), and can aggregate into five different crystalline phases [9][10][11][12], the effect of changing growth conditions on the morphology and the electrical and optical properties of the as-prepared Alq 3 films and nanostructures remains an interesting topic to be investigated [13][14][15][16][17][18].…”

Structures and photoluminescence properties of Alq3 1D materials prepared by an extremely facile solution method

“…[12][13][14][15][16] So far, the Alq 3 nanomaterials were mainly synthesized by vapor depositionbased or solution-based method. [17][18][19][20][21][22][23][24] Compared with the high temperature synthesis process of the vapor phase methods, the solution methods are facile and simple energy-saving route for the fabrication of high-quality Alq 3 nanostructures. 25 Moreover, the solution methods allow people to explore the optical and electronic properties of individual Alq 3 nanorods or nanowires.…”
