吩噻嗪分子是一类拥有较好的刚性结构和大的π共轭体系的杂环分子，具有扭曲的蝴蝶型构象，所以吩噻嗪分子能够阻止π键堆积和链间激基复合物的形成，在有机光电功能材料中显示了很好的应用前景。

Gamophyta A phylum of green algae in which sexual reproduction is by conjugation, e.g.

Gamophyta：是通过接合作用进行有性繁殖的绿藻门植物，例如水绵和鼓藻。

Using the relations between harmonic conjugation elements,we can determine the relations between polar point and polar line more widely.

度量几何中圆的切割线之间所确定的数量关系，推广到射影几何里一般二次曲线中，利用调和共轭元素之间的关系，更广泛地确定了极与极线的相互关系，着重介绍了二次曲线的度量性质与射影性质的内在联系。

Because POTPy and POTPyOT contain pyridine in the main chain, their conjugation length is shorter than that of POTT and POTTOT, leading to the UV and fluorescence spectra of the former are blue-shifted with respect to those of POTT and POTTOT.

POTPy及POTPyOT主链的结构内具有吡啶，导致共轭链的长度缩短，因此在吸收及萤光光谱的位置都比POTT、POTTOT还要蓝位移。

Biological studies indicated that these conjugation could form quinone methide intermediate after illumination.

该类化合物能在光诱导下产生与核酸形成烷基化或交联化的醌的甲基化物中间体。

So it is obvious substituent of large conjugation will lead to red shift of the corresponding absorption wavelength.

显然最大吸收峰会随着侧链共轭程度的增大而红移。

The conjugation of avidin leads to a red shift and an intensity reduction in the fluorescence emission spectra of nanocrystals.

实验中通过光谱的变化证实了CdTe量子点与亲和素之间的结合反应。

It may be due to the following two reasons: 1 High steric hindrance caused by rigid structure of substituted fluorenone preventsthe approach of the chiral reductor;2 The prochiral center is, moreover, linked to two coplanar aromatic rings, which due to strong conjugation are highly electronically similar and thus it becomes extremely difficult to distinguish between them.

主要是以下两个原因：1取代芴酮的刚性结构产生高的空间位阻，阻止了手性催化剂的接近；2潜手性中心旁的两个芳香环不仅立体构型非常相似，而且高度的电子相似，很难被手性配体识别。

The properties concerning the symmetry and conjugation of complex multi-variable telecommunication systems, together with their number of states and transfer intensities are also investigated in the paper.

对于多元件的复杂通信系统，本文分析了其对称性、对偶性方面的性质和在状态数、转移强度数等方面的若干数量关系。

Because of the large conjugation in the structure of terphenyl and cyanogroup, these compounds should have higher birefringence.

由于此类化合物具有三个苯环和氰基组成的大的共轭体系，因此预计它们具有较高的双折射率。
