In summary, a PIL-supported B12 catalyst with a Ru(II) tris-
bipyridine photosensitizer as a visible light-driven photo-
catalyst was successfully synthesized. The hybrid polymer

showed an enhanced emission and
a relatively higher
quantum yield compared to the monomer mixture in the ionic
liquid due to the rigidochromic effect of the polymer, and a
visible light-driven catalytic reaction efficiently proceeded in
the ionic liquids using the hybrid polymer. This catalytic
system is environmentally friendly since the catalyst and the
solvent can be easily reused without any loss of catalytic
efficiency. Therefore, this study will provide a potential appli-
cation of PILs to catalytic chemistry and contribute to the
development of eco-friendly catalysts. Further study on appli-
cation of this PIL-supported B12 catalyst for various molecular
transformations is in progress in our laboratory.
