A new kind of chiral-dendronized binaphthyl-containing polyfluorene derivatives has been synthesized through "click chemistry" efficiently. The resulting copolymers exhibited desirable properties, such as excellent solubility, good thermal stability, and considerably high molecular weights. The photophysical properties of the copolymers were investigated in details, and the results indicated that the combination of chiral binaphthyl unit and bulky dendron could effectively suppress intermolecular packing and aggregation. In addition, the of circular dichroism behavior of these chiral-dendronized copolymers showed a strong Cotton effect at long wavelength (373-379 nm), indicating that the chirality of the binaphthyl units was transferred to the whole polyfluorene backbone.
