Paper 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.
