Hetero Bodipy-dimers as heavy atom-free triplet photosensitizers showing a long-lived triplet excited state for triplet–triplet annihilation upconversion

Author affiliations

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 (1O2) quantum yields (64%). The dimers were used for triplet–triplet annihilation upconversion (quantum yield is up to 3.7%).
