Recently open-chain marocyclic ligand and then lanthanide complexes have attracted much attention mainly because the ligands have the unique molecular structures: changeable chain, inflexibly terminal group and high selectivity and coordination to lanthanide ions.

一个优良的发光器件必须具备以下几个条件：配体对金属离子有较高的选择识别性能；配体含有共轭发色团有利于能量从配体向中心离子转移；配合物具有相对较高的动力学和热力学稳定性。

Indirect photometric detection in CE is often employed for detection of compounds that lack of suitable chromophores.

间接光度检测通常是用来检测并行工程的化合物，缺乏合适的发色团。

The distance between donor and amptor calculated by Forster theory agress with the dimensions of R-PE and APC.

根据Forster能量转移机理，计算得出给体与受体发色团间距离为72A，这一距离与两种蛋白的大小是基本相符的。

In these chromophores, the ring-locked triene employed as a conjugation bridge and the thiobarbituric acid moiety was as an electron acceptor in a D-π-A units.

在这些发色团中，环锁定的三烯和9，10-二氢蒽用作共轭桥，巴比妥酸和甲氧其分别作为吸电子和给电子基，组成非共轭的两个D-π-A单位。

The CL method is useful for the detection of compounds that have no chromophoric groups. Inhibition of CL emission allows the determined of most amino acids at 0.1-1 mM.

使用化学发光的方法对於没有发色团官能基的化合物特别有用，对於大部分胺基酸可测定的浓度值可达0.1~1 mM。

Since exciton transfer and trapping between the chromophoric segments are much more fast process than radiative and non-radiative decay, energy transfer from wide gap segment to narrow-gap site should be highly efficient.

另外，激子在发色团片段的传输和俘获过程比辐射和非辐射性延迟过程快，所以从宽带隙到窄带隙之间的能量转移是很高效的。

Two new kind of energy transfer donor-acceptor dyads consisting of α-naphthoic acid moiety and 9-aminoacridine units linked by tetraethylene glycol or triethylene glycol flexible chain have been synthesized.

本工作分别用聚三乙二醇及聚四乙二醇柔性链将α-萘甲酸酯与9-氨基吖啶连接起来，合成了两种新型二元发色团分子体系，在两个体系中，选择激发α-萘甲酸酯，都可以发生从α-萘甲酸酯到9-氨基吖啶的高效率的单重态-单重态能量传递。

In Chapter 6, five intercalates were synthesized by the ion-exchange reac-tions of some organic chromophores of high β values with 〓 pre-interca-late.

第六章〓β值的有机发色团与〓反应，合成了5个夹层物，探讨了它们的磁性和二阶非线性光学性质。

Developing environmentally friendly high performance new products, mixing different PFBs and polymerizing more monomers with different chromogens are likely to be new areas of research.

开发环保型高性能新产品、不同类型增白剂共混与复配以及多个含不同发色团单体间的聚合有可能成为新的研究热点。

The electronic interaction between the triarylamine units and porphines macrocycle in 4a-c and 10a-c were investigated by UV-vis absorption spectroscopy and fluorescence emission spectroscopy, and the results showed that there was a good energy transfer between triarylamine units and porphines.

经紫外吸收光谱和荧光发射光谱研究表明在化合物4a-c和10a-c分子中三芳胺基团与卟吩母体之间有很好的能量传递，使得三芳胺基团吸收的能量通过卟啉发色团发射出去。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
