A three-dimensional tetrahedral-shaped conjugated small molecule for organic solar cells
We report the synthesis of a novel three-dimensional tetrahedral-shaped small molecule,<b>SO</b>,containing a tetraphenylsilane core and cyanoester functionalized terthiophene arms.A deep lying HOMO energy level of -5.3 eV and a narrow bandgap of 1.9 eV were obtained from cyclic voltamme...
