摘　　要：Room temperature phosphorescence(RTP) has attracted much attention for the applications in information encryption,bioimaging,displaying,and so on.In this work,persistent RTP emission is mainly achieved by the compact face-to-face packing modes with aromatic/perfluoroaromatic interactions.Moreover,it can be further optimized by halogen substitutions with heavy atom effect,electron-withdrawing property,and steric hindrance,resulting in the prolonged RTP lifetime.Furthermore,the multiple fluorine substitutions endowed these luminogens with the water-resistant property,resulting in the maintained RTP emission with water droplets.Therefore,the aromatic/perfluoroaromatic interactions are not only the efficient approach to achieve persistent RTP,but also extend their application to a humid environment or even in water.
