Synthesis of conjugated polymers containing gallium atoms and evaluation of conjugation through four-coordinate gallium atoms

The synthesis and analysis of the electronic states of the main-chain type-organogallium polymers are presented. We synthesized the polymers containing four-coordinate gallium atoms by organometal coupling reactions. The synthesized polymers showed good solubility in common organic solvents and enou...

Description
Summary:The synthesis and analysis of the electronic states of the main-chain type-organogallium polymers are presented. We synthesized the polymers containing four-coordinate gallium atoms by organometal coupling reactions. The synthesized polymers showed good solubility in common organic solvents and enough stability for measuring a series of properties under ambient conditions. In the UV-vis absorption spectra, the electronic interaction through four-coordinate gallium atoms was suggested from the peak shifts of the polymer compared to the model compounds. Theoretical calculation of these molecules supports the extended electronic interaction through the polymer main-chain involving gallium atoms.
