Article Preview

One novel fluorene-based amphiphilic copolymers has been synthesized by Suzuki polycondensation (SPC) with monomer 2,7-dibromo-9,9-bis-(3,6-dioxahepyl)fluorene and 9,9-dioctylfluorene-2,7-bis-(trimethyleneboronate). The copolyfluorenes’ molecular structure is characterized by 1H and 13C NMR as well as elemental analysis. The copolyfluorenes have high molecular weight and narrow molecular weight distribution, at the same time, are found to have good solubility and thermal stabilities. The copolyfluorenes exhibit a UV-visible absorption band in the range of 389-393 nm in both toluene solution and the film state. Upon photo-excitation around the absorption maximum wavelength, their PL spectra show a maximum peaks around at 415-427 nm.
