Pl Emission

ABSTRACTA novel σ-conjugated hyperbranched polysilane is presented, and it has good solubility in common organic solvents. The photoluminescence (PL) emission spectrum of it exhibits an emission maximum at 425nm, which indicates that the polymer emits blue light. The resulting polymer also has good thermal stability and high glass transition temperature. Therefore, it demonstrates a promising application in blue light emitting diodes.
