  Planarized Triarylboranes: Stabilization by Structural Constraint and Their Plane-to-Bowl Conversion

  摘要：

  Triphenylborane and 9,10-diphenyl-9,10-dihydro-9,10-diboraanthracene, constrained to a planar arrangement with methylene tethers, were synthesized by intramolecular multi-fold Friedel-Crafts cyclization. These compounds were stable toward air, water, and amines, despite the absence of steric protection in the vertical direction with respect to the B atoms, and showed characteristic structural, electronic, and photophysical properties. In addition, upon treatment with a fluoride ion, these compounds underwent a plane-to-bowl conversion in a controlled manner.

• A Radical Anion of Structurally Constrained Triphenylborane
  作者：Tomokatsu Kushida、Shigehiro Yamaguchi

  DOI：10.1021/om400560u

  日期：2013.11.25

  the structurally constrained triphenylborane 1 with K produced a radical anion. EPR analysis demonstrated the delocalization of the unpaired electron spin density over the entire π skeleton to a greater extent than is the case for a nonconstrained Ph3B radical anion. DFT calculations indicated that the coplanarization of the benzene rings with the boron plane and the shortening of the B–C bond lengths

  用K对结构上受约束的三苯基硼烷1进行化学还原可产生自由基阴离子。EPR分析表明，与非约束Ph 3 B自由基阴离子的情况相比，未配对电子自旋密度在整个π骨架上的离域程度更大。DFT计算表明，苯环与硼平面的共平面化以及由于结构约束而导致的B–C键长度的缩短是自旋离域的原因。几何结构优化还建议，除了平面构型以外，碗形构型还可以作为可行的局部最小结构。X射线晶体结构分析的确揭示了自由基阴离子1 •–的非平面结构。
• A Planarized Triphenylborane Mesogen: Discotic Liquid Crystals with Ambipolar Charge-Carrier Transport Properties

  DOI：10.1002/anie.201502678

  日期：2015.6.1

  A discotic liquid‐crystalline (LC) material, consisting of a planarized triphenylborane mesogen, was synthesized. X‐ray diffraction analysis confirmed that this compound forms a hexagonal columnar LC phase with an interfacial distance of 3.57 Å between the discs. At ambient temperature, this boron‐centered discotic liquid crystal exhibited ambipolar carrier transport properties with electron and hole
