In molecular semiconductor, the direction of charge carrier transport is consistent with the direction of molecular π-orbital. So the charge carrier mobility is mainly depends on the degree of π-π stacking between adjacent molecules. Therefore, It's important to understand the influence on molecular packing due to structural modification and eventually the relationship between molecular packing and charge transport property. By introducing electron-donating (D) or -accepting (A) functional groups, the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) levels of the materials can be fine-tuned to give unique photophysical and electronic properties. In this context, it would be desirable to develop new classes of molecular materials, which possess fluorinated π-conjugated electronic systems that can be easily prepared, modified and exhibit effective intermolecular interaction for charge carrier transportation.
