| Our group’s previous work and publication on photoinduced interfacial electron transfer studies focused on tricarbonylbipyridinerhenium (I) chloride complexes with flexible saturated bridges functionalized with carboxylic acid and/or thio groups. Our current goal is to synthesize new tricarbonylbipyridinerhenium (I) chloride complexes and attach them to a series of oligomeric phenylethynylene and phenylenevinylene bridges functionalized with either a tricarboxylic acid or trithiol “tripod” triptycene anchor. This will provide precise geometries and bridges containing highly conjugated p-systems to increase ET rates between the metal complex dye and nanoparticle. During this work, a new efficient multiple-step synthesis has been developed to synthesize 4-mono substituted 2,2’-bipyridine ligands; several asymmetrically tetra-substituted triptycenes have been prepared for use as the rigid “tripod” anchor system. |
