Synthesis,charge-separated state characterization of N-methyl-2-(4'-N-ethylcarbozole)-3-fulleropyrrolidine and its derivatives

摘要

N-Methyl-2-(N-ethylcarbozole)-ftdleropyrro lidine and N-methyl-2-(4'-N,N-diphenylaminophenyl)-fulleropyrrolidine were synthesized by 1,3-dipolar cycloaddition under microwave irradiation,which were characterized by MS,1H NMR,IR and UV-Vis.Photoinducedintramolecular electron transfer process from C60 moiety to carbazole moiety has been studied by nanosecond laser flash observed in the near-IR region with a lifetime of 0.28 μs.The electronic spectrum of the C60-TPA was studied by using ZINDO method on the basis of the optimized geometrics with B3LYP/6-31G* program.The results show that the calculated absorption was beyond 440nm,essentially consistent with the experimental value 433 nm.
