The material used in this study is PFO (Poly(9,9-dioctylfluorenyl-2,7-diyl)) in combination with R/S-811 ((R)/(S)-Octan-2-yl 4-((4-(hexyloxy)benzoyl)oxy)benzoate) to examine their optical properties.The study found that with increasing doping ratio, the CD (circular dichroism)spectra and CPL(circularly polarized luminescence) spectra of the materials also increase. Moreover, the efficiency is high (GLUM=0.03). It was also found that annealing with R/S-811 can induce the formation of the β-phase of PFO. The β-phase of PFO has many advantages over the crystalline phase, making it promising for future device applications.掌性添加物激子耦合圓偏振螢光圓二色性β相的PFOchiral additivesCircularly Polarized LuminescenceCircular dichroismexcitonic couplingβ-phase of PFOetd
