Abstract > The self‐assemblies of 2‐decyloxy‐7‐pentadecyloxy‐9‐fluorenone (DPF) are characterized by scanning tunneling microscopy at the liquid/solid interface. Achiral Dimer and chiral S‐like structures are observed in 1‐octanoic acid. The solvent molecule takes part in the self‐assembly via forming COOH?O?C and COOH?COOH hydrogen bonds. When 1‐phenyloctane and n ‐tetradecane are used as the solvents, DPF self‐assembles into chiral Z‐like structure, which are classified into Types I–IV according to the packing styles. For the purpose of exploring the effect of solvent and the competition between these three structures, the self‐assemblies of DPF in mixed solvents and on dry surface are investigated. The results show that S‐like structure is preferred in mixed solvents, while the Z‐like structure has priority when the function of solvent is excluded. DPF molecule shows polarity thus dipole?dipole interaction plays significant roles on forming stable adlayers by forming antiparallel dipole pairs. Furthermore, density functional theory calculation is performed to reveal the driving forces of hydrogen bonds and van der Waals interactions. In light of the popularity of studying chirality at the liquid/solid interface, it is believed that the findings will provide implications for designing chiral systems and will promote the exploration of self‐assembly in the field of surface science. </abstract> </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”XML：Lang =“en”> <标题类型=“main”>抽象</ title> > 通过在液体/固体界面处扫描隧穿显微镜，表征2-癸氧基-7-五戊基氧基-9-芴酮（DPF）的自组装。在1-辛酸中观察到成立二聚体和手性S样结构。溶剂分子通过形成COOHαc和COOHαcOH氢键在自组装中。当1-苯辛烷和 n </ i> - 将溶剂用作溶剂，DPF自组装成手性Z样结构，根据包装件，将其分为I-IV型。为了探索溶剂和这三种结构之间的竞争的效果，研究了DPF在混合溶剂和干燥表面上的自组装。结果表明，在混合溶剂中，S样结构是优选的，而Z样结构在排除溶剂的功能时优先于。 DPF分子显示极性，因此偶极子相互作用在通过形成反平行偶极对形成稳定的亚丁层的显着作用。此外，进行密度泛函理论计算以揭示氢键和范德华相互作用的驱动力。鉴于在液体/固体界面上学习手性的普及，据信该调查结果将为设计手性系统提供影响，并将促进对表面科学领域的自组装探索。 </ p> </摘要> </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-18063/'>《Advanced materials interfaces》</a> <b style="margin: 0 2px;">|</b><span>2018年第1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=Hu Yi&option=202" target="_blank" rel="nofollow">Hu Yi;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Miao Kai&option=202" target="_blank" rel="nofollow">Miao Kai;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Dong Meiqiu&option=202" target="_blank" rel="nofollow">Dong Meiqiu;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Xu Li&option=202" target="_blank" rel="nofollow">Xu Li;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Zha Bao&option=202" target="_blank" rel="nofollow">Zha Bao;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Miao Xinrui&option=202" target="_blank" rel="nofollow">Miao Xinrui;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Deng Wenli&option=202" target="_blank" rel="nofollow">Deng Wenli;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>College of Materials Science and EngineeringSouth China University of TechnologyWushan Road Tianhe District Guangzhou 510640 P.
