Notes:
One novel fluorene-based amphiphilic copolymers has been synthesized by Suzukipolycondensation (SPC) with monomer 2,7-dibromo-9,9-bis-(3,6-dioxahepyl)fluorene and9,9-dioctylfluorene-2,7-bis-(trimethyleneboronate). The copolyfluorenes’ molecular structure ischaracterized by 1H and 13C NMR as well as elemental analysis. The copolyfluorenes have highmolecular weight and narrow molecular weight distribution, at the same time, are found to have goodsolubility and thermal stabilities. The copolyfluorenes exhibit a UV-visible absorption band in therange of 389-393 nm in both toluene solution and the film state. Upon photo-excitation around theabsorption maximum wavelength, their PL spectra show a maximum peaks around at 415-427 nm
