Optical study on the morphology of organic molecules in thin solid films

摘要

Unlike the case of Ir(ppy)3, various aggregates ofrnPtOEP including dimer are formed in PtOEP-dopedrnfilms and neat film. Such a difference is due torndifference of competition among solid state solvationrneffect, dipole-dipole interactions between dopantrnmolecules, and intermolecular covalent bonding.
