摘要：

A photoswitchable fluorescent triad based on dithienylethene and Bodipy was used as a triplet acceptor/emitter for reversible photo-switching 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 (Delta lambda = 268 nm).
