摘要
New armed near-infrared two-photon organic chromophores bearing with o-hydroxy-phenyl-imino groups are presented in this work. These molecules are demonstrated to undergo internal molecular proton transfer in the excited state under irradiation by one-photon absorption and near-IR femtosecond laser two-photon absorption, respectively. The target chromophores show 'naked eye' fluorescence sensing to Zn ions in DMF aqueous solution through the inhibition of excited state intramolecular proton transfer (ESIPT).
