    摘要:
    本文描述了一系列单氨基和二氨基Corannulenes的合成和发光性质。它们从卤代环戊烯的合成很简单。对它们的发光的评估导致三个令人惊讶的发现。首先,各种各样的单氨基和二氨基Corannulenes在溶液中的荧光要比Corannulene本身要强得多,并且4a–j和5a–e在固态时也是荧光的。其次,我们已经确定了diaminocorannulene拥有我们现在在溶液中“典型的”绿-黄荧光视(λ EM = 552纳米),但在固态展品橙红色荧光(λ EM= 615 nm)。第三,我们已经发现,是同时水溶性的并且有用地荧光乙二胺碗烯衍生物(4J,λ EM = 517纳米,QY = 9%; 5e中,λ EM = 560纳米,QY = 11%)。这些令人惊讶的发现对基于氢化萘的材料和生物学应用具有影响。

  • Synthesis and X-ray structural analysis of platinum and ethynyl-platinum corannulenes: supramolecular tectons

    The synthesis and characterization of two direct platinum (1 and 6a/b) and three ethynyl-platinum corannulene derivatives (2, 8 and 9), bearing 2, 4, or 5 square planar platinum centers, are presented. The structure of the bowl bearing substituents remains comparable to corannulene and the dynamic behavior of the bowl inversion as assessed by VT NMR supports a persistent bowl structure in solution. These platinum-corannulenes are well-structured tectons for the future assembly of coordination Platonic polyhedra.

    A new family of π-conjugated oligomers featuring a nonplanar polycyclic aromatic hydrocarbon, corannulene, and a planar aromatic unit, thiophene, is synthesized through an iterative metal-catalyzed coupling protocol. The two structural motifs are connected through an acetylene linkage. In the shorter oligomers, a thiophene unit is attached to one or two corannulenes. In the higher analogues, two, three
    通过迭代金属催化偶联方案合成了一类新的 π 共轭低聚物,其特征是非平面多环芳烃蒌烯和平面芳族单元噻吩。两个结构基序通过乙炔键连接。在较短的低聚物中,一个噻吩单元连接到一个或两个芴烯上。在更高级的类似物中,两个、三个和四个噻吩单元分别与三个、四个和五个芴烯单元交替放置。光物理研究揭示了扩展的 π 效应,这些效应最初随着低聚物长度的变化而增加然后减弱。值得注意的是,发现较长的低聚物对于非线性吸收和发射特性具有高度活性。具有三个芴烯和两个噻吩单元的低聚物表现出 600 GM 的双光子吸收截面和双光子激发的强绿色发光。因此,这项工作引入了在 π 共轭离散低聚物设计中结合平面和非平面芳香基序的概念,建立了这种混合材料的合成可行性,报告了它们的光物理特性,预计将对未来的研究目标产生重大影响,并且发现了蒌烯衍生物在通过 π 桥延伸时可以表现出优异的非线性光学活性。

    The syntheses and properties of corannulenes bearing different numbers and types of ferrocenyl groups are described. Six different monoferrocenylated corannulenes were synthesized, and the crystal structure of 1-corannulenyl-1′-(ferrocenyl)benzene was elucidated by single-crystal X-ray analysis. Further, diferrocenylated corannulenes bearing methyl or trifluoromethyl groups are reported. Buckybowls

  • Structural, Optical, and Electrochemical Properties of Three-Dimensional Push–Pull Corannulenes
    作者:Yi-Lin Wu、Mihaiela C. Stuparu、Corinne Boudon、Jean-Paul Gisselbrecht、W. Bernd Schweizer、Kim K. Baldridge、Jay S. Siegel、François Diederich
    DOI:10.1021/jo302217n
    日期:2012.12.21
    Electrochemically active corannulene derivatives with various numbers of electron-donating 4-(N,N-dimethylamino)phenylethynyl (1-4) or electron-withdrawing cyanobutadienyl peripheral substitutents (5-8) were prepared. The latter derivatives resulted from formal [2 + 2] cycloaddition of cyanoolefins to 1-4 followed by retro-electrocyclization. Conformational properties were examined by variable-temperature NMR and X-ray diffraction and opto-electronic properties by electronic absorption/emission spectra and electrochemical measurements; these analyses were corroborated by dispersion-corrected density functional calculations at the level of B97-D/def2-TZVPP. In CH2Cl2, 1-4 exhibit intramolecular charge-transfer (ICT) absorptions at 350-550 nm and green (lambda(em) similar to 540 nm) or orange (600 nm) fluorescence with high quantum yields (56-98%) and are more readily reduced than corannulene by up to 490 mV. The variation of optical gap and redox potentials of 1-4 does not correlate with the number of substituents. Cyanobutadienyl corannulenes 5-8 show red-shifted ICT absorptions with end-absorptions approaching 800 nm. Intersubstituent interactions lead to distortions of the corannulene core and lower the molecular symmetry. NMR, X-ray, and computational studies on 5 and 8 with one cyanobutadienyl substituent suggested the formation of intermolecular corannulene dimers. Bowl-inversion barriers around Delta G(double dagger) = 10-11 kcal/mol were determined for these two molecules.
  • Tunable Photochemical/Redox Properties of (Phenylthio)<sub>n</sub>corannulenes: Application to a Photovoltaic Device

    The additive substituent effect of phenylmercapto derivatives of corannulene are investigated by spectroscopic, electrochemical, and computational techniques. The per-substituted phenylmercaptocorannulene is incorporated as a replacement for [6,6]-phenyl-C-61-butyric acid methyl ester (PCBM) in a photovoltaic device.
