Herein we designed and synthesized three photoinduced electron transfer ( pet ) phosphoroionophores , ( 1 - bromo - naphthalen - 2 - ylmethyl ) - bis - ( 2 - hydroxyl - ethyl ) - amine ( bnd ) , ( 1 - bromo - naphthalen - 2 - yl - methyl ) - bis - ( 2 - cholor - ethyl ) - amine ( bnc ) and 7 , 16 - bis - ( 1 - bromo - naphthalen - 2 - ylmethyl ) - 1 , 4 , 10 , l3 - tetraoxa - 7 , l6 - diaza - cyclooctadecane and their phosphorescent characteristics were studied , compared with 1 - bromo - 2 - methylnaphthalene . the experimental results showed that strong p hosphorescence could be observed in p - cyclodextrin aqueous solution only at low ph value . this system combined and and not function to produce a three - input inhibit ( inh ) logic gate 实验结果表明,在环糊精水溶液中只有在较低ph时,才能有效抑制分子内的pet过程,使磷光体发射强的磷光,体系的磷光状态为off - on ,同时体系包含了and ( - cdandproton )和not ( o _ 2 )逻辑功能,可作为一种三输入的inhibit逻辑开关。
For the advantages of glucose biosensors are obvious : high specificity , short time , simplicity and low cost of analysis , etc . one of the developments of glucose biosensor is the third generation amperometric enzyme electrode with direct electron transfer , which is commonly prepared by conducting organic salts and conducting polymers 葡萄糖生物传感器具有选择性高、简便、快速的特点,是检测葡萄糖浓度最常用的方法。为提高传感器的性能,一个发展方向是制备直接电子传递的第三代电流型葡萄糖生物传感器。目前把利用导电聚合物或导电有机盐制备的酶电极叫做直接电子传递的生物传感器。
Uv - vis and xrd measurements revealed the facts that there were neither detectable electronic interactions between the two species nor interpenetration and complexion between these two components . while the esr and xps measurement results indicated that there happened a process of photoinduced , oriental and partial electron transfer between chlorodiane blue azo and tiopc molecules 紫外-可见光谱( uv - vis )和x -射线衍射( xrd )测试结果表明基态下两种材料之间没有明显电子态相互作用和两种分子间的穿插与缔合。
The photocatalytic activities of the xw11 / tio2 ( x = p , si , ge ) composite films were tested via degradation of aqueous azo - dyes , congo red ( cr ) and naphthol blue black ( nbb ) . it was observed that the photocatalytic activities of the three composite films are much higher than that of the pure tio2 film , mainly attributed to the synergetic effect between xw11 and tio2 , i . e . , xw11 - catalyzed electron transfer from the conduction band ( cb ) of photoexicited tio2 to itself 结果表明三种复合膜均具有远高于纯tio _ 2膜的活性,主要归因于复合膜材料中多金属氧酸盐和tio _ 2之间存在的协同效应,即作为强电子受体的多金属氧酸盐接受tio _ 2受光激发形成的导带光生电子,延长了空穴-电子的再复合时间,同时自身仍具有光活性。
