文摘

Three stilbazolium salts with A-π-A model have been synthesized and fully characterized. A relative strong intramolecular charge transfer (ICT) transition The excellent third-order NLO response in the near-infrared (IR) region by Z-scan technique using femtosecond laser. The different terminal substituent group of the pyridinium plays a vital role in third-order NLO behavior.
