Soluble fulleropyrrolidines bearing a trialkoxysilyl functionality (methoxy, ethoxy, butoxy, and isopropoxy) have been prepared and characterized. The hydrolysis rate constant for each fulleropyrrolidine was measured with 1H NMR spectroscopy by following the disappearance of selected resonances of the fullerene substrate under the conditions (HCl/H2O/THF) used for the preparation of fullerene-doped
已经制备并表征了带有三烷氧基甲硅烷基官能团(甲氧基、乙氧基、丁氧基和异丙氧基)的可溶性富勒吡咯烷。在用于制备富勒烯掺杂溶胶-凝胶玻璃的条件(HCl/H2O/THF)下,通过跟踪富勒烯底物的选定共振消失,用 1H NMR 光谱测量每种富勒吡咯烷的水解速率常数。已经发现,带有三甲氧基甲硅烷基的富勒吡咯烷 1 比底物 2-7 水解得更快,应该是减少富勒烯球体在溶胶-凝胶玻璃基质中聚集的首选试剂。三乙氧基甲硅烷基衍生物 2,我们用于掺入溶胶-凝胶玻璃的基准富勒吡咯烷,具有第二快的水解速率。(© Wiley-VCH Verlag GmbH & Co.
