英文摘要	Heavy-atom-free triplet photosensitizers are developed by harnessing the thermally active triplet state of carbazolyl dicyanobenzene (CDCB) derivatives and applied to realize visible-to-ultraviolet photon upconversion (UC) via triplet-triplet annihilation (TTA). Demonstrating an annihilator-appending strategy, the designed sensitizers effectively realize TTA UC in polyurethane films with 2,7-di-tert-butylpyrene (DBP) as the annihilator/emitter. The covalently tethered DBP to CDCB is proven critical for achieving the superior sensitizing and UC performance in the solid matrix, essentially by suppressing the reverse ISC and more effectively transferring triplet excitons to free emitters.; National Natural Science Foundation [51573002, 21174004, 21222403]; Ministry of Science and Technology of China [2013CB933501]; SCI(E); ARTICLE; dhzhao@pku.edu.cn; ygma@pku.edu.cn; 2; 1233-1237; 7
