Theoretical study of morphology and charge transport in amorphous Alq3 — •Alexander Lukyanov1, Christian Lennartz2, and Denis Andrienko11Max Planck Institute for Polymer Research, Mainz — 2Department of Scientific Computing, BASF, Ludwigshafen

A force-field for tris(8-hydroxyquinoline) aluminium (Alq3) - a compound widely used in organic light emitting diodes [1] - is developed and verified by comparing classical and first principles (DFT, B3LYP functional) molecular dynamics simulations. This force-field is then used to simulate large scale morphologies of amorphous Alq3. Given the realistic morphology, charge transport in thin films of amorphous Alq3 is analyzed withing the framework of high temperature non-adiabatic Marcus’ theory [2].
