有机电致发光器件代表了未来显示技术的发展趋势,已引起学术界、企业界和政府部门的广泛关注.目前,全色显示是有机电致发光器件商业化的控制因素之一,成为当前研究的一项热点.利用多层器件结构获得的白色电致发光器件,可以有效地提高平板显示器的分辨率,与有机小分子相比,目前的高分子电致发光器件以单层结构为主,这主要是由于共轭高分子发光材料一般通过溶液旋涂法(spincoating)或喷墨打印法(inkinjecting)成膜.
A photo-crosslinkable ployfluorene with oxetane group was synthesized and characterized by NMR, elemental analysis, etc. It was evidenced that the introduction of photocrosslinkable oxetane group has very little effect on the blue-light-emission of polyfluorene. Insoluble polyfluorene films were obtained by crosslinking with the addition of the triarylsulfonium salt photoinitiator under UV irriation. It was revealed that the optoelectronic properties of crosslingked polyfluorene displayed little change compared with uncrosslinked polyfluorenes.
