Photoswitching of triplet–triplet annihilation upconversion showing large emission shifts using a photochromic fluorescent dithienylethene-Bodipy triad as a triplet acceptor/emitter

Abstract

A photoswitchable fluorescent triad based on dithienylethene and Bodipy was used as a triplet acceptor/emitter for reversible photoswitching of triplet–triplet–annihilation upconversion (with Pd(II) tetraphenyltetrabenzoporphyrin as a triplet photosensitizer), which shows green/near IR emission changes with an emission energy difference of 0.79 eV (Δλ = 268 nm).
