摘要：

Conventional studies on polysilanes have dealt with molecular structures on an individual basis and only a few studies have been conducted so far on the intermolecular interaction between different molecules. In order to investigate the intermolecular energy transfer process in detail, time-resolved photoluminescence spectroscopy was carried out against polydihexylsilane (PDHS), polydiphenylsilane (PDPS) and their mixture in powder form. Both the intensity and the lifetime of PDHS emission decreased, while those of PDPS emission increased in the mixed samples. Their mixing-ratio dependence revealed that the resonant energy transfer process from PDHS to PDPS due to multi polar interaction played an important role in light emission characteristics, thus revealing the possibility of their molecular design as interacting pairs and their functional applications.
