High-triplet-level phthalimide based acceptors for exciplexes with multicolor emission

To provide high exciton utilization in organic light emitting diodes, phthalimide derivatives were designed and synthesized as exciplex-forming materials. Due to high triplet levels (2.92–3.11 eV) and ionization potentials (7.18–7.29 eV), the developed phthalimide derivatives were found to be not only appropriate accepting materials for the formation of different color exciplexes but also as bifunctional materials with a satisfactory hole and exciton-blocking abilities. Solid-state blends of the synthesized phthalimides as acceptors and a carbazole containing donors showed exciplex emission. Bimolecular blends exhibited multicolor exciplex emission which covered a visible spectrum from sky-blue to red colors, depending on the donor used. However, the photoluminescence quantum efficiencies of the studied exciplex-forming systems were found to be sensitive to the molecular design of the phthalimides. Acceptor with para-substituted phthalimide showed better exciplex-forming properties in comparison to other compounds. Exciplex-forming blend of (2-(4-benzoylphenyl)isoindoline-1,3-dione) as an acceptor and 1,3-di(9H-carbazol-9-yl)benzene (mCP) as a donor showed the most efficient sky-blue emission with small singlet-triplet splitting (0.06 ± 0.03eV). Such exciplex-forming molecular mixture was implemented as the light-emitting material in the sky-blue organic light emitting diodes which showed the brightness of 2500 cd m?2 and maximum external quantum efficiency of 2.9% due to the employment of both singlet and triplet excitons.

Room temperature palladium-catalyzed decarboxylative acyl/aroylation using [Fe(III)(EDTA)(η2-O2)]3- as oxidant at biological pH

The purple-coloured iron peroxo complex [Fe(III)EDTA(η2- O2)]3- as a novel reagent system for Pd-catalyzed decarboxylative ortho-acylation of acetanilides with α-oxocarboxylic acids at room temperature in aqueous media has been realized. This reaction provides an effective access to ortho-acylacetanilides under mild conditions. Copyright

Intramolecular addition of a hydroxyl to a N-acyliminium system. Application to the synthesis of isoindolo[2,1-a] [3,1]benzoxazine and isoindolo[1,2-c][2,4] benzoxazepine derivatives

The titled compounds were prepared by the reaction of hydroxylated lactam (3a-c) or (10) with p-toluenesulfonic acid in dichloromethane. The ratio of diastereomeric mixtures (4b/5b (2/1) or 4c/5c (2/1) or 11/12 (5/1)) is discussed.

Acid Azides: Part X - New Synthesis and Decomposition Reactions of Phthalimidobenzoic Acid Azides

The o-, m-, and p-phthalimidobenzoic acid azides (IIa-c) have been synthesized via the reaction of the corresponding acid chlorides (Ia-c) with aq.NaN3 in acetone.The base-catalyzed decomposition of IIa-c with aromatic amines and/or hydrazines shows that

Hypolipidemic Activity of Phthalimide Derivatives. 2. N-Phenylphthalimide and Derivatives

A series of substituted N-phenylphthalimide derivatives was synthesized and examined for their ability to lower serum cholesterol and triglyceride levels in mice at 20 (mg/kg)/day, ip.Of the newly synthesized compounds, the most potent compound, o-(N-phthalimido)acetophenone, lowered serum cholesterol 57percent after 16 days and lowered serum triglyceride levels 44percent after 14 days. o-(N-Phthalimido)acetophenone was observed to be active in both normogenic (normal blood lipids levels) and hyperlipidemic mice and normogenic rats.In the latter, the reduction of serum lipids was reversible.The mode of action of this compound appeared to be multiple, including blockage of the de novo synthesis of lipids and acceleration of the excretion of lipids.The lipoprotein fractions of rat blood were reduced significantly in cholesterol, triglyceride, and neutral lipid content after 14 days treatment with o-(N-phthalimido)acetophenone.
