An ink composition for an organic light-emitting device, the ink composition including a luminescent host material and a solvent, wherein the luminescent host material includes at least one compound represented by Formula (1), and wherein the solvent includes at least one selected from an aromatic ether, an aromatic ester, and an aromatic ketone:
wherein, in Formula (1), groups and variables are the same as described in the specification.
It is highly desirable to avoid using rare or toxic metals for oxidative reactions in the synthesis of pharmaceuticals and fine chemicals. Hypervalent iodine compounds are environmentally benign alternatives, but their catalytic use has been quite limited. Herein, the protocol for in situ hypoiodite-catalyzed oxidative rearrangement of chalcones is first realized under mild and metal-free conditions
