通过两步反应合成了一种2-(3-氰基呋喃-2(5H)-亚甲基)丙二腈衍生物TCF-Pyn, 该化合物在MeCN/磷酸缓冲容溶液(PBS) (VV=2∶8, PBS 2×10–2 mol/L, pH=7.4)混合溶液中能高选择性荧光“OFF-ON”识别Pd2+, 发射波长达到近红外区(653 nm). 该探针具有较好的抗干扰能力、较宽的pH适用范围(3~8)和较低的检测限(6.92 μmol/L). 应用研究表明, TCF-Pyn能检测真实水样中的Pd2+, 并可对活细胞中的Pd2+进行荧光成像.

2-(3-Cyano-furan-2(5H)-methylene)malononitrile derivative (TCF-Pyn) was synthesized by a two-step reaction. Compound TCF-Pyn could recognize Pd2+ with a high selectivity, “OFF-ON” fluorescent response and the near-infrared emission (653 nm) in MeCN/PBS ( VV=2∶8, PBS 2×10–2 mol/L, pH=7.4) solution. The probe possesses a good anti- interference capability, a wide pH range (3~8) and a low detection limit (6.92 μmol/L). The application research showed that TCF-Pyn could detect Pd2+ in real water samples and fluorescent image Pd2+in living cells.

Key words: fluorescent probe, near-infrared emission, recognition, Pd2+, cell imaging
