摘　　要：Water-soluble β-cyclodextrin (β-CD)-modified carbon nanocrystals (CNCs) have been synthesized by the reaction of CNCs with mono(6-diethylenetriamino-6-deoxy)-β-CD (DETA-β-CD) and comprehensively characterized by 1H NMR,FT-IR,transmission electron microscopy (TEM) and UV-Vis. DETA-β-CD-modified CNCs (DETA-β-CD-CNCs) are luminescent,and the quantum yield is 8.41%. The photoinduced electron transfer (PET) process between DETA-β-CD-CNCs and (ferrocenylmethyl) trimethylammonium iodide (Fc+) was investigated by means of fluorescence spectroscopy.Water-soluble β-cyclodextrin （β-CD）-modified carbon nanocrystals （CNCs） have been synthesized by the reaction of CNCs with mono（6-diethylenetriamino-6-deoxy）-β-CD （DETA-β-CD） and comprehensively characterized by 1H NMR, FT-IR, transmission electron microscopy （TEM） and UV-Vis.
