  Synthesis, characterization and optical limiting effect of nickel complexes of multi-sulfur 1,2-dithiolene

  摘要：

  Three nickel complexes with a new multi-sulfur 1,2-dithiolene ligand, (n-Bu4N)[Ni(cddt)(2)] 1, (Ph4P)[Ni(cddt)(2)] 2 and [Ni(cddt)(2)] 3 (cddt=4a, 6, 7, 7a-5H-cyclopenta[b]-1,4-dithiin-2,3-dithiolate), have been synthesized and characterized by electrochemical measurements, IR, EPR and UV-Vis-NIR spectroscopies. The crystal structure of complex 2 is determined. Their optical nonlinearities are measured by the Z-scan technique with an 8 ns pulsed laser at 532 nm and all exhibit NLO absorptive abilities. Complexes 1 and 2 both exhibit effective self-defocusing performance (n(2) = -5.81 x 10(-10) esu for 1 and -4.51 x 10(-10) esu for 2). The optical limiting (OL) effects were observed with nanosecond and picosecond laser pulses. The OL capability of complex 3 is superior to C-60 at the same experimental condition in ns measurements.
