英文摘要: The photoluminescence (PL) spectra and UV-Visible absorption spectra of three novel fluorene derivatives solution containing different triphenylamine (TPA) and tetraphenyl-benzene (TPB) groups were systematically investigated. The PL spectra of the acetone/water solution were tested to analyze the capability of suppression concentration quenching (SCQ). The results showed that when water fraction ranged from 50% to 90%, the spectral irradiance of the mixture was obviously increased. Meanwhile, the PL spectra had blue shift due to the blue crystalline aggregation of novel fluorene derivatives, and the blue shift is proportional to the order of crystalline aggregation. Moreover, since the tetraphenyl-benzene and triphenylamine functional groups were tailored to fluorene backbone to suppress the concentration quenching of the fluorene dye and improve the charge carrier transporting ability, the non-doped organic light-emitting devices (OLEDs) were achieved.
