Blue organic light emitting devices(OLEDs) with Alq, PBD, BBOT or F OXD as the electron transport layer were fabricated by a high vacuum multisource type organic molecular deposition system. The effect of various elec...
The band gap( E g) and HOMO level of pyrazoline derivative were obtained by UV Vis absorption spectra and electrochemical cyclic voltammetry methods. The effect of the molecular structure of pyrazoline on the energy b...
