This letter presents excited state intramolecular proton transfer(ESIPT) of new conjugated derivatives containing hydroxy and imino groups.ESIPT occurrence in one photon process is confirmed by well-separated emission band for the derivatives.Twophoton absorption(TPA) induced ESIPT emission has been determined by Ti:sapphire femtosecond laser tuning from 700 nm to 800 nm at the internals of 20 nm.
