Outline of Final Research Achievements |
The following results were obtained in this research. 1) The charge-transfer complexes of oligosilane dendrimers and an electron acceptor were formed, and their UV/Vis spectra were measured. In order to raise the formation constant, synthesis of bicyclo[4.4.4]tetradecasilane having a large cavity was carried out. 2) Oligosilanes containing a phosphorus atom were synthesized. To clarify how the phosphorus atom affects the σ conjugation systems, their electronic properties were studied by UV spectra and theoretical calculations.
