Room-temperature phosphorescent polymers with excitation-wavelength and delay-time emission dependencies

摘要

Novel room-temperature phosphorescent materials based on commercialized poly(4-styrenesulfonic acid-co-maleic acid) salt have been identified with aggregation-induced emission and room temperature phosphorescence emission characteristics. We systematically investigated their excitation-wavelength and delay-time dependencies to provide new insight into the potentiality of these materials for multiple industrial applications, such as optical storage and anti-counterfeit labelling.
