Poly(tetramethylsilarylenesiloxane) derivatives having diphenylfluorene (P1) or diphenyldibenzosilole (P2) skeleton were synthesized. The excellent thermal stability of P1 and P2 was confirmed by the differential scanning calorimetry and thermogravimetry. There were differences in the crystallinity between P1 and P2. The fluorescence quantum yield of P2 was higher than those of P1 and the corresponding monomer indicating the decrease in the tendency toward aggregation by use of dibenzosilole skeleton.
