US Classification:

546 2, 428690, 428917, 546 10, 548101

Abstract:

Certain iridium compounds which may comprise an iridium(III)-ligand complex having the general formula: (C^N)—Ir—(N^N). (C^N) and (N^N) may each represent a ligand coordinated to an iridium atom. The iridium compounds may have a primary phosphorescent photoluminescence peak wavelength in the near-infrared (IR) range. Also, organic devices that use certain iridium compounds. The organic device may comprise an organic layer and the organic layer may comprise any of the iridium compounds disclosed herein. Also, organic devices that use certain metalloporphyrin compounds. The metalloporphyrin compounds may comprise a core porphyrin structure with four pyrrole rings. The metalloporphyrin compounds may have a primary phosphorescent photoluminescence peak wavelength in the near-IR range.

International Classification:

H01L 51/46
H01L 51/48
C07D 487/22

US Classification:

257 40, 540145, 438 82, 257E51026, 257E51041

Abstract:

A compound that can be used as a donor material in organic photovoltaic devices comprising a non-activated porphyrin fused with one or more non-activated polycyclic aromatic rings or one or more non-activated, heterocyclic rings can be obtained by a thermal fusion process. By heating the reaction mixture of non-activated porphyrins with non-activated polycyclic aromatic rings or heterocyclic rings to a fusion temperature and holding for a predetermined time, fusion of one or more polycyclic rings or heterocyclic rings to the non-activated porphyrin core in meso,β fashion is achieved, resulting in hybrid structures containing a distorted porphyrin ring with annulated aromatic rings. The porphyrin core can be olygoporphyrins.

Abstract:

Porphyrin compounds are provided. The compounds may further comprise a fused polycyclic aromatic hydrocarbon or a fused heterocyclic aromatic. Fused polycyclic aromatic hydrocarbon s and fused heterocyclic aromatics may extend and broaden absorption, and modify the solubility, crystallinity, and film-forming properties of the porphyrin compounds. Additionally, devices comprising porphyrin compounds are also provided. The porphyrin compounds may be used in a donor/acceptor configuration with compounds, such as C.
