title: Hetero Bodipy-dimers as heavy atom-free triplet photosensitizers showing a long-lived triplet excited state for triplet-triplet annihilation upconversion.
abstract: Bodipy dimers in which the two different sub-units take an orthogonal orientation were prepared, which show strong absorption of visible light, long-lived triplet excited states (140.9 μs) and high singlet oxygen ((1)O2) quantum yields (64%). The dimers were used for triplet-triplet annihilation upconversion (quantum yield is up to 3.7%).
