  An Efficient Synthesis of Liquid Crystalline Gigantocycles Combining Banana-Shaped and Rod-Like Mesogenic Units

  摘要：

  The synthesis of monodisperse gigantocycles with 63, 87, and 147 ring atoms on the gram scale is described. These molecules were assembled from terphenylene derivatives and long, flexible chains which were mainly aliphatic, with I terminal alkyne groups. The latter allowed for ring formation through oxidative alkyne dimerization in high yield (80-87%). The combination of a rod-like and a banana-shaped mesogen connected by flexible chains within the backbone of a ring gives rise to nematic and smectic mesophases.

  Resistance to Unwanted Photo-Oxidation of Multi-Acene Molecules

  摘要：

  Although long acenes remain a key class of pi-conjugated molecules for numerous applications, photoinduced oxidation upon exposure of the acene to light, often through sensitization of O-1(2), is an important reaction requiring mitigation for most applications. In response to this ongoing challenge, this paper presents a series of four new diarylethynyl-substituted long acenes-three tetracenes and one anthradithiophene-in which the arylene pendants are either benzene, naphthalene, or anthracene. UV/vis and fluorescence spectroscopy reveals that the anthracene-substituted derivatives fluoresce poorly (Phi < 0.01). Although all four long acenes react with O-1(2) at expected rates when an external photosensitizer is included and show the expected changes in fluorescence to accompany these reactions, the anthracene-substituted derivatives resist direct photoinduced oxidation. Through a combination of mechanistic experiments, we conclude that rapid nonradiative decay of the anthracene-substituted derivatives, perhaps because of inter-arene torsions that emerge in theoretical geometry optimizations, makes these compounds poor photosensitizers for O-1(2) or other reactive oxygen species. This discovery opens new design possibilities for extended acene structures with improved photochemical stability.

  We present the efficient synthesis of a new molecular spoked‐wheel structure (MSW‐3). Two derivatives with diameters of approximately 4 nm have been prepared. By highlighting the importance of pseudo‐high‐dilution conditions during cyclization, we were able to access the compounds on a several hundred milligram scale. In addition to the standard characterization (NMR spectroscopy, MS), we describe

  我们提出了一种新的分子辐轮结构（MSW-3）。已经制备了两种直径约4nm的衍生物。通过强调在环化过程中假高稀释条件的重要性，我们能够以几百毫克的规模使用这些化合物。除了标准表征（NMR光谱，MS）之外，我们还通过与适当的模型生色团进行比较来描述荧光MSW的光学性质的详细研究。此外，还通过光和X射线散射实验对溶液中的结构进行了全面研究。扫描隧道显微镜（STM）揭示了分子在高取向热解石墨上的二维组织，并强调了辐条轮结构。通过小角度X射线散射测量的这些分子的直径与STM获得的直径非常吻合，并且与分子建模的结果相符。这证实了辐条的刚性作用，从而产生了形状持久的纳米级扁圆形有机化合物。
