Meso-electron-withdrawing pentamethine cyanines achieve large anti-Stokes blue-emitting triplet-triplet annihilation upconversion

Abstract Developing metal-free triplet-triplet annihilation upconversion systems that operate under far-red excitation and produce efficient blue emission is challenging due to an inherent trade-off between a large anti-Stokes shift and a high upconversion quantum yield. Here we show that introducing electron-withdrawing groups at the meso-position of a pentamethine cyanine scaffold narrows the singlet-triplet energy gap, suppresses photoisomerization, and promotes the intersystem crossing.
