Summary on Grant Application Form
This project is to prepare and investigate the photophysical properties of heterodinuclear complexes which combine a strongly-absorbing d-block unit with a near-infrared (NIR) luminescent lanthanide unit. Preliminary results have shown that sensitised NIR luminescence from the lanthanide occurs by excitation of the d-block chromophore followed by fast energy-transfer. We will exploit this obervsation in several different ways, as follows: We will prepare d-f complexes in which unprecedentedly long wavelengths may be used for excitation, in the range 600 - 1000 nm. These complexes will be of interest as biological probes as both the excitation and resultant emission will be in the long-wavelength region of the spectrum where tissue is relatively transparent. In the first instance we will use easy-to-prepare d-f complexes based on lanthanide tris(diketonate) units as chromophores; once suitable combinations of d and f-block metal components are identified we wil prepare water-stable analogues based on the more strongly binding aminocarboxylate ligands. We will investigate the energy-transfer mechanism (Dexter or FOrster) in homologous series of d-f complexes of increasing length, by measuring the energy-transfer rate constant as a function of metal-metal separation. We will investigate' self-assembly' methods for the preparation of water-stable d-f dyad complexes which will obviate the need for elaborate bridging ligands. We will investigate the use of complexes which have suitable photophysical proeprties in biological conhugates by attaching suitable reactive functional groups such as thiocyanate to their periphery to allow then to be attached to proteins.
