A highly selective Cd2+ sensor of naphthyridine: fluorescent enhancement and red-shift by the synergistic action of forming binuclear complex
摘要:
A new series of fluorophore derivatives from 1,8-naphthyridine have been developed. Compound D1 is the first naphthyridine PET sensor that can signal Cd2+ selectively with fluorescent enhancement and red-shift. A binuclear complex structure has been demonstrated in the D1-Cd2+ complex. (C) 2008 Elsevier Ltd. All rights reserved.
