Summary on Grant Application Form |

The aims of this work are twofold: (i) to prepare a series of molecules with potentially useful optical properties (second- or third-order non-linear optical properties, or strong near-IR absorbance) and evaluate their optical properties; (ii) to use the redox activity of the molecules as a switch for their optical behaviour, such that e.g. their NLO response or IR absorbance can be modulated according to redox state. The NLO-active complexes will be based on dinuclear donor-acceptor molecules containing ferrocenyl donors and oxo-Mo(VI) or imido-Mo(VI) acceptors for second-order effects, and octupolar triangular complexes for both second-order and third-order effects. The near-IR dyes are based on dinuclear complexes whose bridging ligands can undergo reversible 2-electron oxidations to give quinonoidal species. The NLO activity of appropriate molecules in different oxidation states will be studied by a variety of techniques such as degenerate six-wave mixing and Kerr ellipsometry, and it should be possible to relate their NLO properties to their structures and fundamental electronic properties. The near-IR dyes will be studied by spectroelectrochemistry, and suitable candidates will be evaluated as laser dyes or optical limiters.
