摘要
Chiroptical properties and structures of chiral-substituted polyfluorenes have been characterized using UV/Vis, circular dichroism (CD), linear dichroism (LD), photoluminescence (PL), circular polarized photoluminescence (CPPL), linear polarized photoluminescence (LPPL), IR, X-ray diffraction, and polarized microscopy. Light emitting diodes (LED) of these polymers have been made and found to show strong blue-light emission, with the characteristic ratio of the circular polarized electroluminescence (g(CPEL)) up to 7.0 * 10(-2) at 420 nm, which is well above the values found for other conjugated polymers in emission.
