  Structure and UV spectroscopic properties of a novel dendritic oligosilane

  摘要：

  The reaction of (R2MeSi)(2)MeSi-Li (2) [R = SiMe3] with [ClMe2Si](2) yields the double-cored dendritic oligosilane [(RMe2Si)(2)MeSi-SiMe2](2) (4). The structure of 4 was obtained from X-ray diffraction data, which verify a total of 16 silicon atoms in the molecule and a longest chain of 8 silicon atoms. 4 exhibits an absorption maximum in the near UV at 285 nm (e = 5.6 x 10(4)), a wavelength that is significantly longer than that of the linear octasilane Si8Me18 and is the longest observed for structurally well-defined oligosilane dendrimers so far.
