The absorption and fluorescence properties of 1-pyrenyl substituted permethyloligosilanes are reported. The charge transfer in 1-pyrenyltridecamethylhexasilane is explained by electron transfer from the Si-Si Σ orbitals to pyrene in the excited state. Evidence is found for ground state interactions in 1,3-di(1-pyrenyl)hexamethyltrisilane, based on absorption and1H-NMR measurements. The fluorescence properties of l-(1-pyrenyl), 3-(p-N,N-dimethylanilino)hexamethyltrisilane are compared with its carbon analogue l-(1-pyrenyl), 3-(p-N,N-dimethylanilino)propane. Ground state interactions are found for the silicon-bridged donor-acceptor compound. © 1993 Indian Academy of Sciences.
