An organic light-emitting device includes a substrate, an anode and a cathode disposed over the substrate, and a luminescent layer disposed between the anode and the cathode wherein the luminescent layer includes a host and at least one dopant. The host of the luminescent layer is selected to include a solid organic material comprising a mixture of at least two components, one of which is capable of forming both monomer state and an aggregate state.

the products react with amines, in the presence of copper(I) iodide, to form pyrrolo[3,2-c]cinnolines and with hydrazines to give either the same ringsystem or a pyrazolo[4,3-c]cinnoline. Hydrolysis of 3-alkynyl-4-phenoxycinnoline to 3-alkynyl-4(1H)-cinnoline, followed by cyclisation, yields the furo[3,2-c]cinnoline. Attempts to condense 3-halogenocinnolines with alkenes gave variable results: 3-phenyl
