Abstract

The isomerism of the Alq3 molecule was investigated by applying infrared (IR) spectroscopy to two different crystalline phases of aluminium tris(quinoline-8-olate) (α-Alq3 and δ-Alq3). Significant differences between the two phases were found in the IR spectra, which can be explained in terms of the different symmetries of the facial and meridional isomer. Additionally, intermolecular interactions of the Alq3-molecules due to crystallinity were taken into account. The results suggest that α-Alq3 consists of the meridional isomer, while the recently discovered blue luminescent δ-phase is composed of the facial isomer of the Alq3 molecule.
