In this study, we synthesized phenothiazine-based polymers having polar functional group at the chain ends. We then carried out hybridization of the obtained polymers with silica. The weight average molecular weight (Mw) of the obtained polymers were 4000~5700. Thus, there were soluble in organic solvents such as chloroform and THF. The polymers were thermally stable and showed a 10% thermogravimetric loss around 280°C. Fluorescence spectrum of poly[10-(2-ethylhexyl)phenothiazinyl-alt-phenylene] (P1) in THF showed peaks at 490 nm an 520 nm, supporting light blue emission. In addition, a similar emission was confirmed from solid-state P1. In the case of a P1/SiO2 hybrid, the peak of photoluminescence was observed at 480 nm to emit blue light. Thermal stability and weather ability of the P1/SiO2 were also investigated.
