Outline of Final Research Achievements

Triphospha[3]radialene, a cross conjugated compound containing phosphorus, have promising properties for functional dye. However, preparation of the precursor, primary phosphine, was a troublesome problem. Here we developed an easier method for preparation of primary phosphines bearing ferrocenyl moiety. We successfully synthesized tungsten and chromium complex with triphospha[3]radialene moiety as a ligand. The complexation brought about changes of light absorption property, redox potential, and reactivity.
We carried out design and syntheses of novel dye molecules bearing ferrocene moiety and sulfur-carbon double bond. The resulting dye molecules presented excellent light absorption property and stable redox behavior, therefore, they are expected to be applied as functional dyes.
