| 3 | Synthesis and characterization of novel red-emitting copolymers containing fluorene,diketopyrrolopyrrole,and phenothiazine units显示文摘A novel three-component copolymer (PFDP),derived from 9,9-dihexylfluorene,diketopyrrolopyrrole(DPP),and 10-octylphenothiazine,was synthesized through palladium-catalyzed Suzuki polycondensation in good yields. PFDP possessed moderate molecular weight and polydispersity,well-defined structure,and excellent thermal properties with an onset decomposition temperature at 357℃. PFDP in thin film exhibited red photoluminescence from DPP chromophore exclusively,with a peak at 602 nm. Electron-rich phenothiazine units sighificantly improved the injection and transport of holes by incorporating into polymer backbone. Light-emitting device was fabricated in the ITO/PEDOT:PSS/PVK/ polymer/Ba/Al configuration using PFDP as the emitting layer. The device based on PFDP showed red emission [CIE coordinate value (0.62,0.38)] that was close to the standard red (0.66,0.34). The results on electroluminescent performance revealed that PFDP may be a promising candidate for the red emitter with a maximum brightness of 259 cd/m2 and a maximum external quantum efficiency of 0.25%. | QIAO Zhi CAO DeRong LIU QiLin WENG JieNa HE ZhiCai HAN ShaoHu PENG JunBiao | 2009 | Science China Chemistry2009，52，12： | 1 |
| 4 | Green-synthesized,low-cost tetracyanodiazafluorene(TCAF) as electron injection material for organic light-emitting diodes显示文摘Two electron-deficient azaacenes including di-and tetra-cyanodiazafluorene(DCAF and TCAF)with the advantages of deep lowest unoccupied molecular orbital(LUMO),green-synthesis,low-cost,simply purification method,excellent yields have been obtained,characterized and used as electron injection materials(EIMs)in three groups of electroluminescence devices.Device B with TCAF as EIM exhibited the best performance including turn-on voltage of 5.0 V,stronger maximum luminance intensity of 31,549 cd/m2,higher luminance efficiency of 62.34 cd/A and larger power efficiency of 21.74 lm/W which are 0.53,6.7,9.3 and 15.3 times than that of device A with DCAF as EIMs,respectively.The enhanced interfacial electron injection ability of TCAF than that of DCAF is supported by its better electron mobility in electron-only device,deeper LUMO(-4.52 eV),and stronger electronic affinity.Best external quantum efficiency of 16.56%was achieved with optimized thicknesses of TCAF as EIM and TPBi as electron transporting layer.As a new comer of acceptor family,TCAF would push forward organic electronics with more fascinating and significant applications. | Bing Yang Jianfeng Zhao Zepeng Wang Zhenlin Yang Zongqiong Lin Yanni Zhang Jiewei Li Linghai Xie Zhongfu An Hongmei Zhang Jiena Weng Wei Huang | 2019 | Chinese Chemical Letters2019，30，11： | 0 |
