Abstract: We have investigated the two-photon absorption properties of three symmetrical NLO-phores, L1, L2 and L3, having different conjugation lengths as well as different binding sites like cryptand, crown ether and bipyridyl moiety. The TPA properties have been measured by a femtosecond laser at 800 nm, which is in the window of ‘in vivo’ imaging. Upon metal ion binding, the TPA cross-section values are enhanced to different extents depending on the nature of metal ion and the overall architecture of the molecular system as well. The unique CT transition process after metal ion incorporation, along with various conjugation lengths of the NLO-phores, fully elucidates the structure-property relationship of the photophysical properties.
