Abstract
Long-persistent luminescence (LPL) materials have a wide range of applications, such as in architectural decorations, safety signs, watch dials, and glow-in-the-dark toys. Present LPL materials based on inorganics must be processed into powders and blended with polymer matrices before use. However, micropowders of inorganic LPL materials show poor compatibility with common polymers, limiting the mechanical properties and transparency of the composites. Here, a polymer-based organic LPL (OLPL) system that is flexible, transparent, and solution processable is reported. Following low-power excitation at room temperature, this polymer-based OLPL system exhibits LPL after phosphorescence from the donor.

Abstract
A novel comb-shaped fluorinated poly(arylene ether) (cs-FPAE) was prepared from a difluoride monomer, 4-(2,6-difluorobenzoyl)diphenyl ether, with commercial 4,4′-(hexafluoroisopropylidene) diphenol by nucleophilic polycondensation reaction. The number-average molecular weight and polydispersities of cs-FPAE were in the range of 11,000–25,000 and 1.9–2.5, respectively. The refractive index (1.4667–1.5644) and birefringence (0.005–0.02 at 1550 nm wavelength) of spin-coated polymer films were determined using the prism-coupling method.
