Photoinduced Jahn-Teller distortion in crystals of Cu(I) phenanthroline complex

We have studied the effect of lattice induced strained ligand geometry on the excited state dynamics of prototypical Cu(I) based photocatalyst in single crystals using fs-broadband transient absorption spectroscopy. Our results show faster intersystem crossing in crystals (~5 ps) as compared to the solution (~9 ps).
