Enhanced triplet-triplet annihilation upconversion efficiency is achieved with two tris-cyclometalated iridium sensitizers covalently tethered with a pyrene annihilator. The improved sensitizing ability and very long phosphorescence lifetimes (1-2 ms) of these bichromophore molecules are both attributed to the intramolecular energy transfer between the iridium complex and appended pyrene group.
通过将两个三（环金属化）铱敏化剂与一个芘湮灭剂共价连接，实现了三重态-三重态湮灭上转换效率的提高。这些双发色团分子敏化能力的提高以及非常长的磷光寿命（1 - 2毫秒）都归因于铱配合物与连接的芘基团之间的分子内能量转移。
