Effective Photosensitization in Excited-State Equilibrium: Brilliant Luminescence of Tb III Coordination Polymers Through Ancillary Ligand Modifications.

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 Tb III coordination polymers. The photosensitization ability can be considerably altered by changing the ancillary ligands in the Tb III 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.
