Abstract: Organic π\|conjugated molecules have been used in many kinds of optoelectronic devices, in which luminescence efficiency and carrier mobility are two key parameters to decide the optoelectronic device performance. Luminescence efficiency and carrier mobility of organic materials not only depend on the molecular structure, but also the stacking mode in aggregate state structure.In this paper, it is emphasized what is the relationship between the stacking mode of π\|conjugated molecules and their luminescence efficiency and carrier mobility in solid state, and how to adjust the stacking mode of π\|conjugated molecules, especially to realize the stacking mode we desire by the supramolecular interactions.The development of experiment and theory in relvent field is involved in detail.

Key words: π\|Conjugated molecule, Stacking mode, Luminescence efficiency, Mobility, Supramolecular interaction
