摘要: Abstract Four novel Zn(II) terpyridine complexes (ZnLCl2, ZnLBr2, ZnLI2, ZnL(SCN)2) based on carbazole derivative group were designed, synthesized and fully characterized. Their photophysical properties including absorption one-photon excited fluorescence, two-photon (TPA) optical power limiting (OPL) further investigated systematically interpreted the basis of theoretical calculations (TD-DFT). The influences different solvents One-Photon Excited Fluorescence (OPEF) spectral behavior, quantum yields lifetime chromophores have been in detail. third-order nonlinear (NLO) by open/closed aperture Z-scan measurements using femtosecond pulse laser range from 680 to 1080 nm. These results revealed that ZnLCl2 ZnLBr2 exhibited strong showed superior property.
