An organic compound, a three-dimensional organic structure formed by using the organic compound, a separation sieve and an optical layer having the organic structure, and an optical device having the optical layer as an optical amplification layer are provided. The organic structure includes a plurality of organic molecules self-assembled by non-covalent bonding. Each of the unit organic molecules has an aromatic ring, a first pair of substituents being connected to immediately adjacent positions of substitutable positions of the aromatic ring, and a second pair of substituents being connected to immediately adjacent positions of remaining substitutable positions of the aromatic ring. The unit organic molecules are self-assembled by van der Waals interaction, London dispersion interaction or hydrogen bonding between the first and the second pairs of the substituents and by pi-pi interactions between the aromatic rings.

benz-anellated cyclopentadienones (fluorenone (9a), methanophenanthrenone (9b)), yield into phenanthridine (8a) and benzo[lmn]-phenanthridine (8b) in yields > 60%. The results point to a predominant addition of intermediately generated phenyl type radicals 5 to the N atom of the nitrile groups followed by bimolecular H-abstraction of the cyclic imidoyl radicals to 8 (scheme 3).
Novel aryl silicon and aryl germanium host materials, and in particular host materials containing triphenylene and pyrene fragments, are described. These compounds improve OLED device performance when used as hosts in the emissive layer of the OLED.

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.
