Deep-blue organic light-emitting diodes based on a doublet-emission cerium(III) complex

a. Synthetic route for the complex. b. Single crystal structure of the complex shown as ellipsoids at the 50% probability level, where yellow represents Ce, pink represents B, blue represents N, red represents O, grey represents C, and the hydrogens are omitted for clarity. c. Single crystal structure of the complex shown in a space-fill style, where hydrogens are shown in white.
