White light emission based on a single component Sm(Ⅲ) framework and a two component Eu(Ⅲ)-doped Gd(Ⅲ) framework constructed from 2,2'-diphenyl dicarboxylate and 1H-imidazo[4,5-f][1,10]-phenanthroline

摘要

New 1D lanthanide-organic frameworks, [Ln(dpdc)_(1.5)(IP)(H_2O)]_n (Ln = Sm 1, Eu 2, Gd 3; dpdc = 2,2'-diphenyldicarboxylate and IP = 1H-imidazo[4,5-f][1,10]-phenanthroline), were synthesized. White light emission was realized by two approaches: a single component Sm(Ⅲ) framework and a two-component Eu(Ⅲ)-doped Gd(Ⅲ) framework.
