Abstract

Upconverting near-infrared (NIR) light (λ > 700 nm) to violet light (λ < 450 nm) based on triplet–triplet annihilation (TTA) is achieved for the first time by developing a silyl-substituted anthracene violet emitter and its sensitization by an osmium complex showing a singlet-to-triplet (S–T) absorption in the NIR range.
