| Popis: |
Utilization of high density of triplets is important to overcome the dissipation of excitation energy. Triplet–triplet annihilation (TTA) has attracted attention to overcome the conventional limitation for the application of photon upconversion (UC). Synergetic approaches of experimental and computational studies on TTA have been made for efficient TTA-UC in the solid state. Binary solid fabricated by the rapid-drying casting from mixed solution enabled efficient triplet sensitization. Structural modification of emitter molecules has enhanced the performance of TTA-UC in solid. Computational studies clarified the importance of the dimensionality of the exciton diffusion process and orbital overlap in the TTA process. Various extended studies such as solid TTA-UC by near-infrared (NIR) excitation and sensitizer-fixed approach on a solid surface are also presented. |
