Outline of Final Research Achievements

This work describes the design, synthesis, and photophysical properties of X-shaped aryleneethynylenes containing two main group element moieties of B, Si, or P on the side chain.
X-shaped conjugated aryleneethynylenes containing main group element of B, Si, or P were synthesized. These compounds showed unique photophysical properties. For example, these compounds reduce HOMO-LUMO energy gaps compared to the parent π-system, owing to a rise of the HOMO level (P) or a decline of the LUMO level (B, Si, and PO), which is also supported by DFT calculations. Additionally, for example, electronic and optical properties of boron- and phosphorus-containing π-systems were changed by the simple chemical modifications such as coordination of fluoride, oxidation, and others.
