Triplet‐triplet annihilation‐based photon upconversion (TTA‐UC) of near‐infrared (NIR) light to visible light in the solid‐state remains as a great challenge due to the sensitizer aggregation that impedes the efficient triplet energy transfer. Herein, we successfully introduce a molecular sensitizer exhibiting direct singlet‐to‐triplet (S–T) absorption into a new emitter‐based metal‐organic framework (MOF) to achieve an efficient triplet sensitization and a NIR‐to‐visible TTA‐UC in the solid‐state.

通过将S-T吸收敏化剂引入金属有机框架中,实现近红外到可见光子的上转换

在固态中,基于三重态三重态an灭的近红外(NIR)光到可见光的光子上转换(TTA-UC)仍然是一个巨大的挑战,这是因为敏化剂的聚集阻碍了有效的三重态能量转移。在此,我们成功地将一种分子敏化剂展示了直接的单重态到三重态(S–T)吸收,并引入了新的基于发射体的金属有机骨架(MOF)中,从而实现了有效的三重态敏化和近红外-可见TTA-UC在固态。
