▎ 摘　　要

Water-soluble fluorescent graphene quantum dots have been successfully prepared through a top-down approach, that is, starting with graphite, and covalently functionalizing it with pi-extended tetrathiafulvalene. Charge transfer investigations reveal noticeably slower charge recombination when compared with exTTF nano-conjugates featuring carbon nanodots, for which a larger presence of trap states is observed.
