Ruthenium alkynyl-terminated ladder-type oligo(p-phenylene)s

Abstract

The field of nonlinear optics encompasses interactions of electromagnetic fields(light) with matter, these interactions change the nature of the incident light such that new fields with differing phase, frequency, amplitude, polarization, path, or other propagation characteristics are produced. Materials which possess nonlinear optical (NLO) properties are of technological importance in areas that utilize optical devices, with potential applications such as microfabrication, bioimaging, photodynamic therapy, and frequency up-conversion lasing.

In the first part of my PhD work, synthesis of a series of rigidified ladder-type oligo(p-phenylene)s end-functionalized by bis(dppe)-ligated ruthenium alkynyl units. Their optical, electrochemical and spectra electrochemical properties are discussed. Comparison of these results with non-rigidified ruthenium complexes allows for the determination of the effects of rigidification for promising optical properties.

In the second part of this work, a series of rigidified ladder-type oligo(p-phenylene)s end functionalized by nitro acceptor and bis(dppe)-ligated ruthenium unit have been synthesized and characterized. The structure-property relationship of these complexes has been studied.
