Abstract |
Blue-emitting gel via triplet-triplet annihilation-based upconversion (TTA-UC) was prepared by incorporating a bimolecular system consisting of platinum octaethylporphyrin (PtOEP, sensitizer) and 9,10-diphenylanthracene (DPA, emitter) in a self-assembled amphiphilic tri-block copolymer (poly(ethylene glycol)-block-poly(propylene glycol)-block-poly(ethylene glycol), Pluronic P123). The incorporated PtOEP and DPA molecules were successfully achieved by triplet-triplet energy transfer within the self-assembled P123, leading to the upconverted blue emission from DPA caused by TTA. The structure and morphology of the obtained blue-emitting gel were characterized by X-ray diffraction pattern (XRD) and transmission electron microscopy (TEM) image. Optical properties were measured by fluorometer and UV-vis spectrophotometer. |
