Synthesis and characterization of carbene derivatives of Th@C _3v(8)-C₈₂ and U@C _2v(9)-C₈₂: exceptional chemical properties induced by strong actinide-carbon cage interaction.

ABSTRACT: Chemical functionalization of endohedral metallofullerenes (EMFs) is essential for the application of these novel carbon materials. Actinide EMFs, a new EMF family member, have presented unique molecular and electronic structures but their chemical properties remain unexplored. Here, for the first time, we report the chemical functionalization of actinide EMFs, in which the photochemical reaction of Th@C _3v(8)-C₈₂ and U@C _2v(9)-C₈₂ with 2-adamantane-2,3'-[3H]-diazirine (AdN₂, 1) was systematically investigated. The combined HPLC and MALDI-TOF analyses show that carbene addition by photochemical reaction afforded three isomers of Th@C _3v(8)-C₈₂Ad and four isomers of U@C
