Chinese Journal of Polymer Science

1 Aims and Scope Chinese Journal of Polymer Science （CJPS） is a bimonthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Fosong Wang and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communucations and has the current name since 1985.     

锑(Ⅲ)-2-(3,5-二溴-2-吡啶偶氮)-5-二乙胺基酚-溴代十六烷基三甲胺的络合物吸附波

在pH5.3的HAc－NaAc、2－（3，5－二溴－2－吡啶偶氮）－5－二乙氨基酚（3，5－Br2－PADAP）、溴代十六烷基三甲铵（CTMAB）溶液中，用线性扫描示波极谱法可得到锑（Ⅲ）的络合物吸附波。峰电位为－0.70V（vs．SCE）。二阶导数档峰高与Sb（Ⅲ）浓度在3．3X10-8～2．5X10－6mol／L范围内呈线性关系。检出限为8．2X10-9mol／L。用多种电化学方法研究了极谱波的性质及电极反应机理。络合物组成为Sb（Ⅲ）：3，5－Br2－PADAP＝1∶2。加入CTMAB可消除试剂峰且提高灵敏度。试验了30多种离子对峰电流的影响，用流基棉分离干扰离子。方法已用于矿样中锑的测定。     

锡(Ⅳ)-偶氮邻苯二酚苯基荧光酮-吐温-80体系分光光度法测定岩石中微量锡

pH值在7.0-8.5的范围内，锡与偶氮邻苯二酚苯基荧光酮、吐温－80形成络合物，其最大吸收峰556nm，摩尔吸光系数2.9×10^5L·mol^-1·cm^-1，锡的含量在0－6μg/25mL范围内遵守比耳定律，本方法对干扰离子的影响和消除进行了研究，本方法已被用于岩石样中锡的测定，结果满意。     

High—Efficiency Organic Double—Quantum—Well Light—Emitting Devices Using 5,6,11,12—Tetraphenylnaphthacene Sub—monolayer as Potential Well

The double-quantum-well organic light-emitting devices of indium-tin-oxide (ITO)/NPB (50nm)/rubrene (0.05nm)/NPB (4nm)/rubrene (0.05nm)/Alq3 (50nm)/LiF (0.5nm)/Al were fabricated, in which N,N-bis-(1-naphthyl)-N,N‘-diphenyl-1,1‘-biphenyl-4,4‘‘‘‘‘‘‘‘-diamine (NPB) is used as a barrier potential or hole transport layer, tris (8-hydroxyquinoline) aluminium (Alq3) used as electron transport layer, and 5,6,11,12-tetraphenylnaphthacene (rubrene) as a potential well and emitter. The brightness can reach 18610cd/m^2 at 13V. The maximum electroluminescent efficiency of the device was 6.61cd/A at 7V, which was higher than that of common dope-type devices. In addition, the electroluminescence efficiency is relatively independent of the drive voltage in the range from 5 to 13V.
