presence of hexamethylphosphorous triamide (HMPT) or hexaethylphosphorus triamide (HEPT) results in fullerene derivatives incorporating HMPT or HEPT ylides. The ylide derivatives exhibit unusual electronic absorptions in the visible region (435−660 nm), likely due to the presence of the ylide moiety. Electrochemical studies revealed that the first reductive potential of these compounds was more negative
乙炔二甲酸二甲酯(DMAD)在六甲基磷三酰胺(HMPT)或六乙基磷三酰胺(HEPT)的存在下与C 60的反应产生了结合了HMPT或HEPT基团的富勒烯衍生物。叶立德衍生物在可见光区域(435-660 nm)表现出异常的电子吸收,这可能是由于叶立德部分的存在所致。电化学研究表明,相对于C 60(ΔE = 130 mV)和简单的Bingel加合物(ΔE = 90 mV)而言,这些化合物的首次还原电势更负。氨基磷酸酯副产物,是通过向C 60中添加HMPT或HEPT产生的然后水解,相对于C 60表现出在可见光区无特征的吸收光谱和更负的第一还原电势(ΔE = 70 mV)。
