摘要: Abstract One mono‐adduct and three novel multi‐adduct analogs of C60‐diphenylaminofluorene C60(>DPAF) n derivatives were synthesized characterized by various spectroscopic methods. Optical absorption these samples indicated a systematic increase in relative intensity the fluorene band centered at 415 nm as number DPAF addend increases. Fluorescence chromophore all 4 (n = 1), 5 (n = 2), 6 (n = 3), 7 (n = 4) o‐dichlorobenzene chloroform was found to be efficiently quenched direct covalent bond attachment moieties fullerene cage facilitates efficient intramolecular electron or energy transfer processes.
