Abstract
We have synthesized new types of the H-shaped molecules with bis(tert-butyldimethylsilylbithienyl)silyl and bis(tert-butyldimethylsilylterthienyl)silyl units by using Sonogashira coupling reaction. UV–Vis absorption and fluorescence properties of these molecules have been investigated. We have found that the disilanylene group in the H-shaped molecule with bis(tert-butyldimethylsilylbithienyl)silyl units plays an important role in enhancing the quantum efficiency in solution.
