We have been studying the nonlinear optical (NLO) properties of metal alkynyl complexes, in studies ranging from small complexes to dendrimers. While our early focus was on molecular quadratic and cubic NLO coefficients, materials with multi-photon absorption (MPA) properties have become of increasing interest for applications such as microfabrication, bioimaging, photodynamic therapy, and frequency upconversion lasing. We have recently been exploring the MPA behaviour of rod-like, star, and dendritic OPVs and oligo(phenylenethynylene)s (OPEs) bearing bis(diphosphine)ruthenium moieties (e.g. examples in figure); the results of these studies will be presented.
