摘要：

The absorption and emission spectra of pyrene substituted tri- and hexa-silanes are reported. Sigma(Si-Si) --> pi*(pyrene) charge-transfer fluorescence is observed for 1-(1-pyrenyl) tridecamethylhexasilane but not for 1-(1-pyrenyl)hepta-methyltrisilane. This is explained by the difference in oxidation potential of the tri- and hexa-silane chain. The emission of the bichromophoric systems 1,6-di(1-pyrenyl)dodecamethylhexasilane and 1-(4-N,N-dimethylanilino)-6-(1-pyrenyl)dodecamethylhexasilane is mainly determined by the sigma --> pi* charge transfer. 1,3-di-(1-pyrenyl)hexamethylhexasilane and 1-(4-N,N-dimethylanilino)-3 (1-pyrenyl)hexamethyltrisilane show respectively excimer and exciplex emission.
