Abstract
The synthesis and characterisation of two new nickel bis(dithiolene) oligomers is described. The third-order non-linear optical index of refraction (n2) and real-to-imaginary ratio has been determined using the z-scan technique for one ditholene system as a guest in a poly(methylmethacrylate)(PMMA) host. A real-to-imaginary ratio (n2/β) of 4.3 was determined at a concentration of 5 × 1020 molecules cm–3.Keywords
