Based on a through bond energy transfer (TBET) between rhodamine and naphthalimide fluorophores, a fluorescent ratiometric chemosensor L was designed and prepared for highly selective detection of Fe(3+) in aqueous solution and in living EC109 cells. These significant changes in the fluorescence color could be used for naked-eye detection. The reversibility established the potential of the probe as chemosensor for Fe(3+) detection.
基于罗丹明与萘二甲酰亚胺荧光团之间的穿键能量转移（TBET），设计并制备了一种荧光比率化学传感器L，用于在水溶液和活的EC109细胞中高选择性地检测Fe(3+)。荧光颜色的这些显著变化可用于裸眼检测。这种可逆性确立了该探针作为检测Fe(3+)的化学传感器的潜力。
