A novel donor-π-acceptor-π-donor type (D-π-A-π-D') Schiff base derivative (L) has been designed and synthesized. The structure of L is confirmed by single-crystal X-ray diffraction analysis as well. The photophysical properties of compound L were comprehensively investigated by using both experimental and theoretical methods. The results indicate that L exhibits large Stokes shift and moderate two-photon action (2PA) cross-section in the near infrared (NIR) region. Furthermore, the confocal microscopy imaging study demonstrates that compound L could penetrate into cells and target the cellular mitochondria compartment. Due to its low cytotoxicity, compound L provides a promising tool for directly lighting up the mitochondria compartment in living HepG2 cells.
一种新型给体-π-受体-π-给体型（D-π-A-π-D'）席夫碱衍生物（L）已被设计和合成。L 的结构也通过单晶 X 射线衍射分析得到证实。通过实验和理论方法综合研究了化合物 L 的光物理性质。结果表明，L 在近红外（NIR）区域表现出大的斯托克斯位移和中等的双光子作用（2PA）截面。此外，共聚焦显微镜成像研究表明，化合物 L 可以穿透细胞并靶向细胞线粒体区室。由于其低细胞毒性，化合物 L 为直接照亮活 HepG2 细胞中的线粒体区室提供了一种有前途的工具。
