摘要:A flurophore-phenothiazine derivative {2-[(10-ethyl-10H-phenothiazin-3-yl)-methylene] malononitrile, abbreviated as L} is designed, synthesized, and characterized by single crystal X-ray diffraction analysis. Further, L is used to couple with Au NPs to construct L-Au nanohybrid. Upon the coupling effect between L and Au components, blue-shifted photoluminescence with an obvious increased FL lifetime has been achieved. Surface enhanced Raman scattering analysis reveals that L molecules couple with Au NPs through S atoms. The coupling "hot spot" and the energy match between the Femi level of Au NPs and the frontier molecular orbital energy of L are effective factors in distributing the photogenerated electrons at the interface to tune the optical property.
