Abstract(in English) | Polysilanes have unique properties as one-dimensional semiconductors due to the delocalization of the σ electrons along Si main-chain. Except for excitonic emission peculiar to the delocalized states, detailed correlation between molecular structure and luminescent properties has not been understood yet. In order to study the structural dependence of the emission characteristics, we performed time-resolved photoluminescence measurement of polysilanes with alkyl- and phenyl-based side-chains and those with branched main-chains as a function of temperature. An energy flow from the main-chain to a visible emission band, the dependence of energy relaxation process on temperature and on the branching ratio became clear phenomenologically. |
