Synthesis of dilactone bridged terphenyls with crankshaft architectures
摘要:
Three highly fluorescent dilactone bridged terphenyls with crankshaft architectures have been synthesized. This general class of compounds is relatively unexplored. These compounds have been characterized by fluorescence and UV-vis spectroscopy. For all three compounds, a direct correlation between the rigidity of the terphenyl system and the strength of absorption and emission of light has been observed. Preliminary studies have indicated that compounds with this architecture have the potential to be useful as pH-driven molecular switches and/or sensors with instant fluorescence attenuation at high pH values.

A material for a hole-transport layer includes a monoamine compound. The first aromatic group, the second aromatic group, and the third aromatic group are bonded to the nitrogen atom of the monoamine compound. The first and second aromatic groups each independently include 1 to 3 benzene rings. One or both of the first and second aromatic groups have one or more hydrocarbon groups each having 1 to 12 carbon atoms each forming a bond only by the sp

hybrid orbitals. The total number of the carbon atoms in the hydrocarbon group in the first or second aromatic group is 6 or more. The total number of the carbon atoms in all of the hydrocarbon groups in the first and second aromatic groups is 8 or more. The third aromatic group is a substituted or unsubstituted monocyclic condensed ring or a substituted or unsubstituted bicyclic or tricyclic condensed ring.

Primary benzylic boronate esters are useful intermediates in organic synthesis, but these reagents cannot be prepared by hydroboration. The benzylic C-H borylation of methylarenes would be a method to form these products, but such reactions without neat methylarene or a directing group are unknown. We report an approach to divert the borylation of methylarenes from aromatic positions to benzylic positions
主要的苄基硼酸酯是有机合成中有用的中间体,但这些试剂不能通过硼氢化反应制备。甲基芳烃的苄基 CH 硼酸化将是形成这些产物的一种方法,但这种没有纯甲基芳烃或导向基团的反应是未知的。我们报告了一种以甲硅烷基硼烷为试剂和含有缺电子菲咯啉作为配体的新型铱催化剂将甲基芳烃的硼酸化从芳族位置转移到苄位位置的方法。该系统相对于相应的芳基硼酸酯选择性地形成苄基硼酸酯。由菲咯啉连接的 Ir 二硼基单甲硅烷基复合物被分离并确定为催化剂的静止状态。机理研究表明,这种复合物在动力学上有能力成为催化过程中的中间体。各种 Ir 配合物催化的苄基和芳基 CH 硼化的动力学研究表明,芳基 CH 硼化速率随着 Ir 催化剂金属中心电子密度的降低而降低,但苄基 CH 硼化速率对Ir 催化剂金属中心的电子密度。动力学和计算研究表明,这两种硼酸化反应对金属中心的电子密度程度的反应不同,因为它们发生在不同的转换限制步骤中。已知芳基
Synthesis and Characterization of Monoisomeric 1,8,15,22-Substituted (A<sub>3</sub>B and A<sub>2</sub>B<sub>2</sub>) Phthalocyanines and Phthalocyanine−Fullerene Dyads
Synthesis and characterization of three phthalocyanine−fullerene (Pc-C60) dyads, corresponding monoisomeric phthalocyanines (Pc), and buildingblocks, phthalonitriles, are described. Six novel bisaryl phthalonitriles were prepared by the Suzuki−Miyaura coupling reaction from trifluoromethanesulfonic acid 2,3-dicyanophenyl ester and various oxaborolanes. Two phthalonitriles were selected for the synthesis
描述了三种酞菁-富勒烯(Pc -C 60)二元化合物,相应的单体异构体酞菁(Pc)和结构单元邻苯二甲腈的合成和表征。通过Suzuki-Miyaura偶联反应,由三氟甲磺酸2,3-二氰基苯基酯和各种氧杂硼烷制备了六种新颖的双芳基邻苯二甲腈。选择两种邻苯二甲腈用于合成A 3 B-型和A 2 B 2-型酞菁。邻苯二甲腈4具有庞大的3,5-二-叔-在邻苯二甲酸位置的丁基丁基取代基,仅迫使一种区域异构体形成并大大提高了酞菁的溶解度。邻苯二甲腈8在α位具有3-苯基丙醇侧链,使得可以进一步修饰侧基。合成的单体异构体A 3 B和A 2 B 2型酞菁通过丙二酸残基的连接而被修饰。最后,富勒烯通过一个或两个丙二酸桥与酞菁共价连接,生成Pc -C 60二元组。由于酞菁类化合物的异构体结构和增加的溶解度,化合物的NMR光谱质量得到了显着提高,从而使详细的NMR分析成为可能。合成的二元化合物具有不同的酞菁和富勒烯取
