would serve as precursors to cage polyyne C60H6 and its perchloro derivative C60Cl6, respectively, were prepared. In the negative mode laser desorption mass spectra of the cyclophanes, the polyyne anions C60H6− and C60Cl6− were detected. Moreover, size-selective formation of C60+ as well as C60− was also observed, indicating the possible polyyne cyclization mechanism to form the fullerene cage.
制备了由六个[4.3.2]丙三烯单元稠合的[16.16.16](1,3,5)环丙烷,分别用作笼型多炔C 60 H 6及其全氯衍生物C 60 Cl 6的前体。在环芳的负模式激光解吸质谱,所述聚炔烃阴离子Ç 60 ħ 6 -和C 60氯6 -进行检测。此外,C的尺寸选择性形成60 +,以及为C 60 -中也观察到,表明可能的聚炔烃的环化机理,以形成富勒烯笼。
