This project is in the general field of analytical and surface                  chemistry and in the subfields of photochemistry and                            electrochemistry.  Chemical synthetic methods will be employed                  to prepare a wide variety of linked intramolecular electron                     transfer systems that have unique properties absent in                          non-linked systems.  The complexes are based on trisbipyridine                  (II) as a light-harvesting photocenter.  This photocenter is                    covalently linked via flexible linkages to N,N'-diquaternary-                   2,2'-bipyridinium as an electron acceptor and/or N-alkyl                        phenothiazine as an electron donor.  In other series, triply                    bridged heterodinuclear ruthenium/rhodium complexes with                        relatively rigid linkages will be studied.  Ground state                        properties will be characterized by electrochemical,                            spectroelectrochemical and spectroscopic methods.  Electron                     transfer rates will be determined by time-resolved emission and                 absorption spectroscopy.                                                                                                                                        Combined electrochemical, photochemical and photophysical                       studies of linked donor/acceptor photosensitizer systems will                   lead to a better understanding on the molecular level of                        light-induced electron transfer systems.  The results will aid                  in the design of more efficient molecular systems for                           converting light emergy into useful chemical energy.
