The Janus-faced chromophore: a donor-acceptor dyad with dual performance in photon up-conversion

An electron donor-acceptor dyad based on BODIPY (acceptor) and anthracene (donor) plays either the role of sensitizer or emitter in triplet-triplet annihilation photon up-conversion (TTA-UC). This Janus-like behavior was achieved via altering the relative ordering of charge-transfer and local excite...

Zusammenfassung:An electron donor-acceptor dyad based on BODIPY (acceptor) and anthracene (donor) plays either the role of sensitizer or emitter in triplet-triplet annihilation photon up-conversion (TTA-UC). This Janus-like behavior was achieved via altering the relative ordering of charge-transfer and local excited state energies in the dyad through the polarity of TTA-UC media. BODIPY-anthracene dyad shows two "faces" in triplet-triplet annihilation upconversion (TTA-UC) process: behaves either as a triplet sensitizer, or as a singlet emitter, depending on the media polarity.
