A series of sulphur linked 1,8–naphthalimide–phenyl/naphthalene conjugates (NTs 1–6), were designed, synthesized and fully characterized by NMR and HRMS. The effects of aromatic substituent in NTs 1–6 on the absorption, fluorescence and aggregation induced emission (AIE)/ aggregation induced emission enhancement (AIEE) were explored. NTs 1–6 were shown AIE/AIEE behavior in THF: water mixtures. Molecular flexibility provided by the thioether linkage override steric hindrance in the 2,6–dimethylbenzenethiol–naphthalimide conjugate. The nanoaggregates of NTs 1–6 formed in tetrahydrofuran/water (1:9, v/v) solutions are observed by transmission electron microscope (TEM), and dynamic light scattering (DLS). |
