| Covalently linked donor-acceptor complexes have attracted much attention because of their photochemical applications. Chemical intuition suggests that covalently linked donor-acceptor complexes would show faster energy and/or electron transfer than hydrogen bonded complexes. However, recent literature report suggests that hydrogen-bonded complexes' may exhibit transfer rates that are comparable to those of covalently linked complexes. Hydrogen-bonded complexes could be easily synthesized by self-assembly, an advantage over conventional covalently linked donor-acceptor complexes. Ruthenium (donor) and osmium (acceptor) complexes containing a hydroxy-phenanthroline derivative have been synthesized and characterized by electrochemical and spectroscopic methods. This presentation will describe the synthesis of the complexes, their spectroscopic properties, the transfer mechanism and the rate of transfer between the donor and acceptor centers. |
