Title: Hetero Bodipy-dimers as heavy atom-free triplet photosensitizers showing a long-lived triplet excited state for triplet-triplet annihilation upconversion. Author: Wu W, Cui X, Zhao J. Journal: Chem Commun (Camb); 2013 Oct 11; 49(79):9009-11. PubMed ID: 23969566. 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%).[Abstract] [Full Text] [Related] [New Search]
