摘要

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 us) and high singlet oxygen (~1O_2) quantum yields (64%). The dimers were used for triplet-triplet annihilation upconversion (quantum yield is up to 3.7%).
