    Efficient preparation and properties of triazole-linked corannulene derivatives
    摘要:
    In this study, we explore the potential of copper(I)-catalyzed cycloaddition reaction between azides and terminal alkynes to prepare corannulene-rich materials. For this purpose, a practical route is established to yield corannulene-based azide building blocks. The newly prepared corannulene-azides are then coupled with known corannulene-alkynes. The chemical yields of the dimerization reactions ranged from 80 to 90%. In this way, a number of triazole-linked corannulene derivatives varying in the geometry, length, and the triazole-content are prepared. These results suggest that alkyne-azide click reaction can serve as a useful synthetic tool in the preparation of corannulene-rich discrete oligomers as well as polymers. (C) 2012 Elsevier Ltd.

  • Structure/Energy Correlation of Bowl Depth and Inversion Barrier in Corannulene Derivatives:  Combined Experimental and Quantum Mechanical Analysis

    correlating the structure (bowl depth) and the energy of bowl inversion. Substituents placed in the peri positions are repulsive and flatten the bowl, thus causing a decrease in the bowl inversion barrier. Conversely, annelation across the peri positions causes a deepening of the bowl, thus an increase in the bowl inversion barrier. Barriers between 8.7 and 17.3 kcal/mol have been measured, and their
    一系列具有不同碗深度的芴烯衍生物的合成允许进行相关结构(碗深度)和碗反转能量的研究。放置在周围位置的替代物具有排斥性并使碗变平,从而导致碗反转障碍的降低。相反,周围位置的退火会导致碗变深,从而增加碗反转障碍。已经测量了 8.7 到 17.3 kcal/mol 之间的势垒,并且已经使用各种从头计算方法计算了它们的结构。假设单个 corannulene 衍生物的能量分布适合混合四次/二次函数,从中可以导出碗深度和遵循四次函数的反转势垒的经验相关性。

    The geometry imposed by the coordination sphere around the metal, together with the choice of the “arms” can be advantageously used to build corannulene-based molecular tweezers, which show great affinities for C60 and C70, as revealed by NMR titration experiments.

    The supramolecular dimerization of tetraanionic corannulene is utilized as a self-assembly motif for the construction of highly charged, buckybowl-based supramolecular oligomers. Oligomers of up to 7 units (3900 g mol−1) of reduced dicorannulenic monomers are identified and characterized by various NMR techniques, and the reversibility of their assembly is established through the concentration dependence of their molecular weight and the effect of monofunctional chain-stoppers.
