The different intercalation behavior of 5,10,15,20-tetrakis(1-methylpyridinium-4-yl)porphine into α-zirconium phosphate and γ-zirconium phosphate was investigated.

比较了水溶性卟啉meso-四(4-N-甲基吡啶基)卟啉对具有不同层间距和结构的层状磷酸锆的插层行为。

Porphyrins is a general term of the homologue and derivative of porphine with substituting groups at the outside ring, becoming metalloporphyrins promptly after two protons on its nitrogen are replaced by the metal ion.

卟啉是卟吩环外带有取代基的同系物和衍生物的总称，当其氮上两个质子被金属取代后即成金属卟啉。

At first,the amino group of amino acid esters interacts with the carboxyl group of the amino acid residue of this porphyrinatozinc to form 1:1 adducts.

氨基酸酯的氨基首先与氨基酸残基的羧基作用形成1：1的加合物，然后与锌卟啉的中央锌原子配位形成1：2的加合物，客体分子与主体分子上的氨基酸残基之间的排斥作用以及主客体之间的色散力作用是主体分子能识别客体分子的另外两种作用。

These substituents are either small groups such as phenoxy groups,aryls,cyclic secondary amines,cyano groups,and halogens or large functional moieties such as PDI,Phthalocyanines, porphyrins,BODIPY,cyclodextrin,Fullerene,calixarene,and so on.

这在过去的工作中，人们把一些小分子的，如酚氧基、仲胺基、苯基、氰基以及卤素氟、氯、引入到PDI中，同时也把一些较大功能团，如PDI本身、卟啉、酞菁、环糊精、BODIPY、杯芳烃、富勒烯等和PDI连接在一起。

Wheares under buffer pH5.2, there is no strong static electricity and instead being a longer wavelength movement; SDS\'s participation just restricts the relative movement of heme\'s ethylene; a new fluorescent peak forms and the reduction of enzymatic activity is due to the packing of micella\'s formation.

强变性的阴离子表活剂SDS与带净正电荷和弱负电荷的SBP(处于pH2.6和4.2缓冲液中)有强烈的静电力作用，酶活力丧失，二级结构变化，荧光强度增加，特征Soret发生蓝移，卟啉环的π-π*共轭的分裂能增大；而当SBP带净负电荷(pH5.2)时，没有静电吸引力，Soret带发生红移；SDS的引入只是限制了血红素上乙烯取代基的运动，使其与卟啉环共轭：极性环境的变化导致产生新的荧光峰；酶活力因胶团包裹作用而有下降。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
