Blue-to-UVB photon upconversion (UC) enabled by a benzene-based annihilator is presented for the first time. The annihilator's unprecedented singlet-excited energy of 4.15 eV was successfully employed to activate inert carbonyls via a subsequent FRET energy transfer. This UC-FRET reaction scheme was directly monitored by laser techniques and exploited in lab-scale NMR experiments demonstrating its potential in light-to-chemical energy conversion.

由苯基歼灭剂实现的蓝色到 UVB 上转换、溶剂敏化和具有挑战性的键激活

首次提出了由基于苯的歼灭剂实现的蓝色到 UVB 光子上转换 (UC)。歼灭剂前所未有的 4.15 eV 单线态激发能量被成功用于通过随后的 FRET 能量转移激活惰性羰基。这种 UC-FRET 反应方案由激光技术直接监测,并在实验室规模的核磁共振实验中得到利用,证明了它在光能到化学能转换方面的潜力。
