摘要：
Benzodithiophene (BDT)-based star-shaped molecule (12TBDT) was synthesized by Stille coupling reactions. The star-shaped molecule shows high decomposition temperature (447 degrees C), low-lying HOMO level (-5.52 eV), and wide UV vis absorption between 300 and 530 nm (E-g = 2.36 eV). DFT results show that the electron density of the HOMO and LUMO are localized on the thiophene and BDT groups. To the best of our knowledge, this is one of the earliest reports on star-shaped benzodithiophene molecules.
