Photophysics of linear and bent p-conjugated oligomers incorporating MLCT chromophores. Walters, K., A., Ley, K., D., & Schanze, K., S. Abstracts of Papers, 220th ACS National Meeting, Washington, DC, United States, August 20-24, 2000, 2000. abstract bibtex Two new series of p-conjugated oligomers have been synthesized with an areneethynylene repeat structure that incorporates a 2,2'-bipyridyl subunit for inorg. MLCT chromophore ligation. The 5-LP oligomers and 5-ReP -ReI(CO)3Cl complexes are similar to a previously reported oligomer series that contains biphenyl rather than monophenyl repeat units. The 4-L oligomers and 4-Re rhenium complexes are substituted at the 4,4' positions of the central bipyridine, creating a \"bent\" oligomer. A detailed study of the oligomer and rhenium complex photophysics has been performed, and several of these results are presented. Of key interest is a temp.-dependent excited-state equil. between an oligomer-based 3p,p* state and a metal-to-ligand charge transfer (3MLCT) state. This equil. is revealed when the 3MLCT energy is raised with the use of the -ReI(CO)3(NCCH3) chromophore. [on SciFinder (R)]
