A heptamethine-based charge-transfer dye was designed based on previous evidence of triplet state formation in orthogonal charge-transfer partners and calculations suggesting the formation of a charge-transfer state in heptamethine dye derivatives.
Photon upconversion is facilitated by the generation of a charge transfer transition in the interface of a coupled QD–thiol system.
