2.METHODS The products were isolated by silica gel chromatography, flash chromatography ODS Rp 18 and semipreparative HPLC. The structures of three major products have been established by spectroscopic evidence (IR, UV, EI MS, FAB MS, 1HNMR , 13 CNMR , 13 C 1H COSY, HMBC spectrum).
方法　以FeCl3 为氧化剂进行反应 ,用硅胶低压正相柱色谱、反相色谱以及半制备高压液相色谱等手段对反应物进行分离 ,经IR ,UV ,EI MS ,FAB MS ,1HNMR ,13CNMR及13C 1HCOSY ,HMBC等光谱方法鉴定化合物的结构。收藏指正
3.The reaction flash evaporation method of nickel presented in this paper is without equipment of BEV. For produced systems with G/ITO/NiOx in 2M KOH solution the measured results of transmissivity spectrum to saturated colour state and bleached state indicate that the changes of transmissivity are over 60% for eye peak response (λ=550nm ). Its electrochromic response and depositing rate are also better than those of rf sputtering technology.
本文介绍的金属镍反应闪蒸方法无需电子束设备，所制备的G／ITO／NiOx系统在2MKOH溶液中的饱和着色和漂白的透射光谱测试表明，相对于人眼峰值响应（λ＝550nm）的透射率变化范围达60％以上，薄膜的电致变色响应速度、沉积速度也优于反应溅射工艺。收藏指正
