Abstract

The third-order nonlinear susceptibility, (chi) ⁽³), for a series of complexes of 3,5- ditertbutyl-o-benzoquinone (dbsq), [M(dbsq)₂ where M equals Pd or Pt], o- mercaptophenol (mp), {[TBA][Ni(mp)₂]}, or 1,3-dithiol- 2-thione-4,5-dithiol (dmit), {[TBA][M(dmit)₂] where M equals Ni or Pd}, have been measured in CH₂Cl₂ solution by retroreflection DFWM technique at 1064 nm. The results indicate large (chi) ⁽³) values of the order of 10^-11 esu at concentration levels of 10¹⁸ molecules/cm³. These values are up to two orders higher than those found for other sulphur donor dithiolenes and nitrogen donor ligand systems, although the linear absorption is also higher.
