제목 Studies on electron transport properties of naphthalene diimide-based small molecules with different terminal groups
초록 We have investigated on molecular designing of naphthalene diimide (NDI)-based n-type small molecules to optimize electron transport properties and solution processability. Through simple substitution of terminal alkyl, aromatic, or fused aromatic units at N and N’ positions of NDI derivatives, we could effectively control the molecular stacking modes and resulting charge carrier mobility. Furthermore, solubility of NDI derivatives was significantly improved by substituting homochiral asymmetric solubilizing groups at the terminal position of the NDI structure. Based on our findings on the relationship between molecular structures and electron transport properties and solubility, we report on the elaboration of vertical and lateral electron mobility of NDI derivative series and demonstrate their use for the efficient perovskite solar cells as electron transport layers.
