ABSTRACTTime-resolved degenerate four-wave-mixing studies have been conducted on solutions of transition-metal complexes of benzenedithiol using a 35 ps Nd:YAG laser operating at 1.064 μm. The nonlinear optical properties of the first-row Co(d7), Ni(d8), and Cu(d9) and the d8 group Ni and P t transition metal complexes are discussed.

Environmental contextDiffusive gel layer techniques can measure fluxes of chemical species in aqueous environmental media. Nanoparticulate metal complexes are small enough to penetrate gels, but their diffusive response is much slower than that of the free metal ions. Hence, time-resolved analysis of the diffusive flux of the complex sample is proposed as a chemical speciation tool for the nanodomain. AbstractFor a fully labile complex system, the diffusive gradients in thin film (DGT) metal flux approaches the fairly simple limit defined by the joint diffusion of the free metal ion and the complex species in the gel layer. Natural soft nanoparticulate complexes, such as those with humics and fulvics, generally enter the DGT gel phase and some of them may even be adsorbed by the gel matrix. The time characteristics of the DGT response are affected by a lower rate of diffusion, as well as by possible accumulation of nanoparticulate species in the gel layer. Several cases are discussed in some detail on the basis of numerical analysis of the diffusion process. If the difference between the diffusion coefficients of the free metal ion and the nanoparticulate complex is sufficiently large, the time-resolved DGT flux allows for distinction between these two types of species.

The nature of the lowest excited state of rhenium and copper complexes of dipyrido[3,2- a:2′ ,3′-c]phenazine (Dppz) has been determined using Resonance Raman, Time- Resolved Resonance Raman Spectroscopy and Spectroelectrochemistry. Comparison of spectroelectrochemical data and excited state data show that for the complexes studied no reduced ligand bands are observed in the excited state spectra thus the lowest excited states are all Ligand Centred in nature. The use of substituents at the 11 and/or 12 position of the ligand has no effect on the excited state ordering.
