•Two novel Nickel(II) complexes were designed, synthesized and fully characterized.•The Ni(II) complexes have higher electron delocalization.•The Nickel(II) complexes exhibit large two-photon absorption in narrow near-infrared range.•The Nickel(II) complexes exhibit superior optical power limiting property.•It possesses large values of the real part of the cubic hyperpolarizability χ(3).
Two novel Nickel(II) complexes (NiL21 and NiL22) with remarkable two-photon absorption (TPA) and optical power limiting (OPL) properties were synthesized and fully characterized. Single crystals were obtained and solved by X-ray diffraction analysis. Their photophysical properties had been further investigated both experimentally and theoretically. The third-order nonlinear optical (NLO) properties (TPA and OPL) were investigated by open/closed aperture Z-scan measurements using femtosecond pulse laser in the range from 680 to 1080 nm. The results revealed that the two Nickel(II) complexes exhibited strong two-photon absorption and superior optical power limiting properties, which are much better than that of the free ligands.
