摘要

Abstract > The complex formation of bis(18‐crown‐6)stilbene ( 1 ) and its supramolecular donor‐acceptor complex with <fi>N</fi> , <fi>N</fi> ′‐bis(ammonioethyl) 1,2‐di(4‐pyridyl)ethylene derivative ( 2 ) with alkali and alkaline‐earth metal perchlorates has been studied using absorption, steady‐state fluorescence, and femtosecond transient absorption spectroscopy. The formation of 1 ?M <fi>n</fi> + and 1 ?(M <fi>n</fi> + ) <sub>2</sub> complexes in acetonitrile was demonstrated. The weak long‐wavelength charge‐transfer absorption band of 1 · 2 completely vanishes upon complexation with metal cations because of disruption of the pseudocyclic structure. The spectroscopic and luminescence parameters, stability constants, and 2‐stage dissociation constants were calculated. The initial stage of a recoordination process was found in the excited complexes 1 ?M + and 1 ?(M + ) <sub>2</sub> (M?=?Li, Na). The pronounced fluorescence quenching of 1 · 2 is explained by very fast back electron transfer ( <fi>τ</fi> <sub>et</sub> ?=?0.397?ps). The structure of complex 1 · 2 was studied by X‐ray diffraction; stacked ( 1 · 2 ) <sub> <fi>m</fi> </sub> polymer in which the components were connected by hydrogen bonding and stacking was </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract Type =“main”> <标题类型=“main”>抽象</ title> > BIS（18-Crown-6）斯蒂莱（ 1 </ b>）的复杂形成及其超分子具有<FI> N </ FI>，<FI> N </ FI>'-BIS（氨基乙基）1,2-DI（4-吡啶基）乙烯衍生物（ 2 / b>），供体 - 受体复合物已经使用碱和碱土金属高氯酸盐使用吸收，稳态荧光和飞秒瞬态吸收光谱进行了研究。形成 1 </ b>Δm <fi> n </ fi> + </ sup>和 1 </ b>？（m <fi> n </证明了乙腈中的<sub> 2 </ sub>复合物。由于假环结构的破坏，<B> 1 </ B>·<B> 2的弱的长波长电荷转移吸收带，在与金属阳离子的粘结后完全消失。计算光谱和发光参数，稳定性常数和2阶段解离常数。在激发的复合物中发现重新编制过程的初始阶段 1 </ b>Δm + </ sup>和 1 </ b>？（m + </ sup >）<sub> 2 </ sub>（m？=？li，na）。通过非常快的回电子传递（<fi>τ</ fi> <sub> et </ sub>Δ=Δ=？ 0.397？PS）。通过X射线衍射研究了复合物的络合物 1· 2 </ b>;堆叠（ 1 </ b>· 2 </ b>）<sub> <fi> m </ fi> </ sub>聚合物，其中通过氢键连接和堆叠 </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-35546/'>《Journal of Physical Organic Chemistry》</a> <b style="margin: 0 2px;">|</b><span>2018年第2期</span><b style="margin: 0 2px;">|</b><span>共10页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Volchkov Valery V.&option=202" target="_blank" rel="nofollow">Volchkov Valery V.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Rusalov Mikhail V.&option=202" target="_blank" rel="nofollow">Rusalov Mikhail V.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Gostev Fedor E.&option=202" target="_blank" rel="nofollow">Gostev Fedor E.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Shelaev Ivan V.&option=202" target="_blank" rel="nofollow">Shelaev Ivan V.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Nadtochenko Viktor A.&option=202" target="_blank" rel="nofollow">Nadtochenko Viktor A.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Vedernikov Artem I.&option=202" target="_blank" rel="nofollow">Vedernikov Artem I.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Efremova Asya A.&option=202" target="_blank" rel="nofollow">Efremova Asya A.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Kuzmina Lyudmila G.&option=202" target="_blank" rel="nofollow">Kuzmina Lyudmila G.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Gromov Sergey P.&option=202" target="_blank" rel="nofollow">Gromov Sergey P.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Alfimov Michael V.&option=202" target="_blank" rel="nofollow">Alfimov Michael V.;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Ya.
