摘　　要：A new rhodamine B derivative T1 has been rationally synthesized and displayed selective Pd（Ⅱ）-amplified absorbance and fluorescence emission above 540 nm in methanol-water. Upon the addition of Pd（Ⅱ）, the spirolactam ring was unfolded and a 1：1 metal-ligand complex formed, which can be used for ＇＇naked-eyes＂ detection. In addition, fluorescence imaging experiments of Pd^（2＋） in HepG2 living cells showed its valuable application in biological systems.A new rhodamine B derivative T1 has been rationally synthesized and displayed selective Pd（Ⅱ）-amplified absorbance and fluorescence emission above 540 nm in methanol-water.
