| 1 | Alkali metal salts doped pluronic block polymers as electron injection/transport layers for high performance polymer light-emitting diodes显示文摘A series of alkali metal salts doped pluronic block copolymer F127 were used as electron injection/transport layers (ETLs) for polymer light-emitting diodes with poly[2-(4-(3′,7′-dimethyloctyloxy)-phenyl)-p-phenylenevinylene] (P-PPV) as the emission layer. It was found that the electron transport capability of F127 can be effectively enhanced by doping with alkali metal salts. By using Li2CO3 (15%) doped F127 as ETL, the resulting device exhibited improved performance with a maximum luminous efficiency (LE) of 13.59 cd/A and a maximum brightness of 5529 cd/m2, while the device with undoped F127 as ETL only showed a maximum LE of 8.78 cd/A and a maximum brightness of 2952 cd/m2. The effects of the doping concentration, cations and anions of the alkali metal salts on the performance of the resulting devices were investigated. It was found that most of the alkali metal salt dopants can dramatically enhance the electron transport capability of F127 ETL and the performance of the resulting devices was greatly improved. | ZHANG Kai LIU ShengJian GUAN Xing DUAN ChunHui ZHANG Jie ZHONG ChengMei WANG Lei HUANG Fei CAO Yong | 2012 | Science China Chemistry2012，55，5： | 5 |
| 2 | A novel crosslinkable electron injection/transporting material for solution processed polymer light-emitting diodes显示文摘A novel crosslinkable water/alcohol soluble conjugated polymer PFN-C containing oxetane groups and aminoalkyl groups in the side chains has been developed and used as highly efficient electron injection and transporting material for polymer light-emitting diodes (PLEDs). The unique solubility in polar solvents and crosslinkable ability of PFN-C render it a good can- didate for solution processed multilayer PLEDs. It was found that PFN-C can greatly enhance the electron injection from high work-function metal cathode, due to its pendant amino groups. As a result, PLEDs with PFN-C/Al cathode exhibited compara- ble device performance to the devices with Ba/Al cathode. The resulting green light-emitting device showed promising perfor- mance with a maximum luminance efficiency of 13.53 cd A-1. | LIU ShengJian ZHONG ChengMei ZHANG Jie DUAN ChunHui WANG XiaoHui HUANG Fei | 2011 | Science China Chemistry2011，54，11： | 4 |
| 3 | Study on Pretreatment during Simultaneous Determination of Sulfonamides and Chloramphenicols in Honey显示文摘[Objective]This study was conducted to establish a new UPLC-MS method for simultaneous detection of sulfonamides and chloramphenicols in honey.[Method]In this experiment,0.2%formic acid-acetonitrile was used as an extractant to simultaneously extract chloramphenicols and sulfonamides from drugs.The extract was then loaded and extracted with an efficient separation column Oasis~?PRiME HLB.After nitrogen blow-concentration and dissolution with mobile phase,the extract was loaded on UPLC and detected by MS.[Result]There was a good linear relation in the range of 0.1-10ng/ml for chloramphenicols,with a correlation coefficient of 0.991,while sulfonamides had a good linear relation in the range of 0.5-50ng/ml.The lowest detection limit of chloramphenicols and sulfonamides were 0.1and 0.5μg/kg,respectively.The recoveries were in the range of 82.50%-101.2%,with RSDvalues in the range of 3.2%-4.0%.[Conclusion]This method is simple and fast with low detection limit,high recovery and good reproducibility,and could be used for simultaneous detection of residual chloramphenicols and sulfonamides in honey. | Guangfeng ZHONG Xiaoling LIU Chengmei WANG | 2017 | Agricultural Biotechnology2017，6，2： | 2 |
