Photocured Blended Films of Diarylfluorene having Naphthalene Moieties and TiO<sub>2</sub> with High Refractive Indices

We developed photocured films from a blend of TiO2 and dinaphthylfluorene derivatives having acryl and naphthalene groups and photoinitiators with high refractive indices. The curing properties of the blends were strongly affected by the irradiation conditions. We successfully fabricated films with high refractive indices (1.767 at 589 nm) and a high thermal stability (5% weight loss temperature: 265 oC).
