  Synthesis of chiral [60]fullerene-steroid bisadducts using steroid templates

  摘要：

  The double [4+2] cycloadditions between [60]fullerene and steroid-appended dibenzoates 7 and 8, the reaction sites of which were controlled by diols in chiral template molecules, afforded [60]fullerene-steroid bisadducts 11 and 12 regio- and chiroselectively. CD spectroscopic studies of 11 and 12 indicated that the magnitude of the Cotton effects changes reflecting the chiral structure of the steroid moiety in 11 and 12. (C) 1999 Elsevier Science Ltd.

  [reaction: see text] The Diels-Alder reaction of various dienophiles such as C(60) with a pseudorotaxane having a sultine moiety afforded corresponding [2]rotaxanes in moderate yields. The introduction of a porphyrin moiety on the wheel component considerably enhanced the efficiency of the end-capping reaction with C(60).

  Intramolecular photoinduced charge-separation and charge-recombination processes in a covalently connected C60-(spacer)-N,N-bis(biphenylyl)aniline (C60-spacer-BBA) dyad, in which the center-to-center distance of the electron acceptor and electron donor is 15 A, have been studied by time-resolved fluorescence and transient absorption methods. The observed low fluorescence intensity and the short fluorescence

  共价连接的C60-（间隔基）-N，N-双（联苯基）苯胺（C60-间隔基-BBA）二价分子内的分子内光诱导电荷分离和电荷复合过程，其中电子的中心距受体和电子供体为15 A，已通过时间分辨荧光和瞬态吸收方法进行了研究。在PhCN和THF中观察到的低荧光强度和二元组C60部分的短荧光寿命表明，电荷分离是通过C60部分的激发单重态以非常快的速度和高效率进行的。PhCN和THF中的纳秒瞬态吸收光谱显示在880和1100 nm处有宽吸收带，这归因于C60（*-）-间隔物-BBA（* +）。在室温下，PhCN和THF中电荷分离态的寿命为330-360 ns。根据温度与电荷重组速率常数的关系，重组能量估计为0.77-0.87 eV，这表明电荷重组过程位于抛物线的马库斯区。随着温度降低，由于C60（*-）-间隔基-BBA（* +）溶剂化的增加，经由C60部分的激发三重态的电荷分离贡献增加。
