The fluorescence of uranyl originated from electronic transitions (S 11 -S 00 and S 10 -S 0v , v = 0-4) of the ligand-to-metal charge transfer (LMCT) process is an intrinsic property of many uranyl coordination compounds. However, light-induced regulation on fluorescence features of uranyl hybrid materials through photoactive functional groups is less investigated. In this work, the photoactive vinyl group-containing ligands, (E)-methyl 3-(pyridin-4-yl)acrylate and (E)-methyl 3-(pyridin-3-yl)acrylate, have been used in the construction of urany...
