Effective Photosensitization in Excited‐State Equilibrium: Brilliant Luminescence of TbIII Coordination Polymers Through Ancillary Ligand Modifications

Von Wiley-VCH zur Verfügung gestellt

Molecular photosensitizers exhibit efficient light-absorbing capabilities in photo-functional materials. This work reports effective photosensitization at excited-state equilibrium using TbIII coordination polymers. The coordination polymers are composed of TbIII ions (as emission centers), hexafluoroacetylacetonato (as a photosensitizer ligand), and phosphine oxide-based bridges (as ancillary ligands). The ancillary ligand controls the excited state equilibrium between the photosensitizer and TbIII, allowing the construction of TbIII coordination polymer with high TbIII emission quantum yield (≥70 %).

Abstract

Invited for this month′s cover are the collaborating groups of Yuichi Kitagawa, Yasuchika Hasegawa, Tetsuya Taketsugu, and co-workers at Hokkaido University. The cover picture shows a photosensitizer that has a long excited-state lifetime and provides strong emissions for TbIII coordination polymers. The photosensitization ability can be considerably altered by changing the ancillary ligands in the TbIII coordination polymers. The results provide new insights on the design of photosensitizers for improving the properties of photo-functional materials. More information can be found in the Research Article by Y. Kitagawa, Y. Hasegawa, and co-workers.
