A new 1,3,4-oxadiazole-contanining rhenium(I) complex, with the formula [Re(CO)a(Bphen)(PTOP)], (Bphen = bathophe- nardine, PTOP = 4-(5-p-tolyl-1,3, 4-oxadiazd-2-yl) pyridine), is synthesized and character...A new 1,3,4-oxadiazole-contanining rhenium(I) complex, with the formula [Re(CO)a(Bphen)(PTOP)], (Bphen = bathophe- nardine, PTOP = 4-(5-p-tolyl-1,3, 4-oxadiazd-2-yl) pyridine), is synthesized and characterized by elemental analysis, IR, 1H NMR, UV-vis and luminescence spectroscopy. The double-layer electroluminescence devices based on the Re(l) complex have been fabricated by spin-coating technique. The turn-on voltage, maximum efficiency, and brightness for green emission obtained from the devices are 9 V, 2.1 cd/A and 165 cd/m^2, respectively.展开更多
A new europium(Ⅲ) complex, tris(dibertzoylmethanate){ 1-[9-hexyl-9-carbazole]-2-(2-pyridyl)-bertzimidazole}europium(Ⅲ) [Eu(DBM)a(CPyBM)] was synthesized and used as an electron-acceptor and electron-tran...A new europium(Ⅲ) complex, tris(dibertzoylmethanate){ 1-[9-hexyl-9-carbazole]-2-(2-pyridyl)-bertzimidazole}europium(Ⅲ) [Eu(DBM)a(CPyBM)] was synthesized and used as an electron-acceptor and electron-transport layer in organic photovoltaic (PV) device. Power conversion efficiency achieved from the device was 1.04% under illumination with 365 nm UV light at 1.6 mW/cm^2. Compared with the previous reported devices based on Eu(Ⅲ) complexes, the PV performances were improved. The working mechanism of the organic PV device was discussed.展开更多
