The 1,1′-disila-4,4′-biphenyl species 1, the first molecule bearing directly connected two silaaromatic rings, was synthesized and characterized by its spectroscopic and X-ray crystallographic data. The UV−vis spectrum of 1 showed not only a red shift but also a 6-fold increase in absorbance of the longest absorption maximum in comparison with those of Tbt-substituted silabenzene, indicating that the
合成了1,1'-disila-4,4'-
联苯物种1,它是第一个直接连接两个
硅芳香环的分子,并通过其光谱学和X射线晶体学数据对其进行了表征。与Tbt取代的
硅苯相比,UV-vis光谱1不仅显示红移,而且最大吸收最大值的吸光度增加了6倍,这表明通过连接两个芳族化合物的单键进行共轭的概念环甚至适用于
硅芳香族体系。
