| Research Abstract |
Sterically crowded triarylphosphines bearing functional sites, especially electron acceptors, were synthesized as model compounds of the functional materials, and were revealed to exhibit properties typical of triarylphosphines such as fluorescence with large Stokes shift as well as those inherent to π-conjugated systems. Synthesis, structure, properties, and reactivities of sterically crowded triarylphosphines, arsines, stibines, and their derivatives such as oxides, onium salts, and radical cations were investigated. Influence of the steric crowding on the structure and properties is largest for three-coordinated trivalent compounds.
