用法和例句

The results of the stacking interaction between the adenine and the polypyridine ligands showed that the stacking strength followed the order of PIP>IP>phen, which was.

用pH电位滴定法测定二元配合物Cu(ATP)2(ATP为三磷酸腺苷)和三元配合物CuL(NTP)2[NTP=ATP或UTP(三磷酸尿苷),L=phen(邻菲咯啉),IP(咪唑并[4,5f]邻菲咯啉)或PIP(2-苯基咪唑并[4,5-f]邻菲咯啉)]的稳定常数,研究CuL(ATP)2中多吡啶芳环L与腺嘌呤之间的堆积作用-结果表明,堆积作用的大小顺序为PIP>IP>phen,这与多吡啶芳环的结构有关

Comparison of the stability constants of ternary complexes Cu(UTP)L 2- with those of the binary complexes CuL 2+ ,shows stacking interaction between the aromatic ring of the N base and the pyrimidine moiety of UTP.

用pH电位滴定法测定了三元混配配合物Cu(UTP)L2-(L=吡啶,3,4-二甲基吡啶,异喹啉)在水溶液中的稳定常数,并通过比较三元混配配合物Cu(UTP)L2-和二元配合物CuL2+的稳定常数,指出在UTP的嘧啶环和芳香氮碱的芳香环之间存在着堆积作用,而且在相同的实验条件下,Cu(UTP)L2-分子内的堆积作用弱于Cu(ATP)L2-分子内的堆积作用

Comparing these data with those of the corresponding complexes containing ammonia instead of pyridine like ligands, it has been found that an intramolecular stacking interaction exists between the pyridine like lig.

用pH电位滴定法测定了水溶液中二元配合物ML2+和三元混配配合物M(ATP)L2-的稳定常数,将结果与氨的相应值比较,发现所研究三元混配配合物中吡啶类配体的芳环与ATP的嘌呤环之间存在着分子内堆积作用,这种作用与中心金属离子的配位层结构有

On the infrequence O-H…π stacking interaction in the crystal structure;

晶体结构中罕见的O-H…π堆积作用

The regioselectivity of these reactions was studied via analysis of these stable conformations, finding that there exists the π-π stacking interaction between the ester group and the benzyl aromatic-ring in the molecule.

采用模拟退火方法得到了三个活性酯分子的低能构象,并采用Hartree-Fock方法在6-31G*基组水平上对其进行全几何优化,通过对构象的分析对产生区域选择性的因素进行了初步探讨,发现分子一端的酯基团与侧链的苄基芳环之间存在着π-π堆积作用,并导致了低能构象中相关原子对两端羰基形成不同程度的屏蔽,并由此产生了反应的区域选择性。
