Abstract

Detailed degenerate four wave mixing (DFWM) studies of four molybdenum complexes, cis-Mo(CO)₄ (PPh₃)₂, cis-Mo(CO)₄(AsPh₃)₂, cis-Mo(CO)₄(PPh₂Np)₂ and cis-Mo(CO)₄(P(OPh)₃)₂ are reported in this paper. Upon exposure to air/oxygen, the χ⁽³⁾ values of solutions of the first three complexes increase dramatically with time. However, when excess free ligand is added to any of the solutions, no additional increase in the χ⁽³⁾ value is observed. Hence, it is possible to obtain solutions with high χ⁽³⁾ values by first oxidizing the solution and then adding excess ligand to stabilize the solution. Further, the increase in the χ⁽³⁾ values of the solutions parallels the increase in the linear absorption, but it is unclear whether the increased linear absorption plays any role in the increase in the χ⁽³⁾ values of the solutions. This study also shows how degenerate four wave mixing can be used as a very sensitive technique to detect the chemical change in a solution when the third order optical nonlinearities of the reactant and product are very different.
