摘要：

The structure of a sexithiophene derivative end-substituted by two bulky triisopropylsilyl groups has been determined in an attempt to better understand the relationship between structure and the electronic and optical properties of polythiophenes. The synthesis and structural characterization of derivative are described in detail and the unusual crystal system that involves staggered parallel arrays of molecules and a strong deviation from coplanarity of the pi-conjugated backbone is discussed.
