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%).

摘要

制备了两个不同亚基呈正交取向的 Bodipy 二聚体，其具有可见光强吸收、长寿命三重态激发态（140.9μs）和高单线态氧（(1)O2）量子产率（64%）。这些二聚体用于三重态-三重态湮灭上转换（量子产率高达 3.7%）。
