Fluoranthene-based triarylamines as hole-transporting and emitting materials for efficient electroluminescent devices

Electroluminescent materials based on the fluoranthene core and containing triarylamine segments were synthesized and characterized by IR, NMR, UV-Vis, and emission spectroscopic, electrochemical, and thermal studies. The electronic absorption and emissio

Synthesis, structure, and photophysical properties of highly substituted 8,8a-dihydrocyclopenta[a]indenes

(Chemical Equation Presented) A triple round: A palladium-catalyzed cyclotrimerization of 1,2-diarylacetylenes has been developed to synthesize highly substituted 8,8a-dihydrocyclopenta[a]indenes. One such cycloadduct (1) displays unusual aggregation-induced emission with a strong blue fluorescence (see picture). The structures of the products have been confirmed by X-ray crystal analysis.

Synthesis of fluoranthenes and indenocorannulenes: Elucidation of chiral stereoisomers on the basis of static molecular bowls

Cycloaromatization of a peri diyne with an external alkyne provides a general route to indenofused polynuclear aromatics. Fluoranthenes 9 (or 13) are easily accessible in good to excellent yields (75-99%; 18 examples) from the reaction of symmetric (or as

SYNTHESIS OF PHENYL-SUBSTITUTED FLUORANTHENES BY A DIESEL-ALDER REACTION AND THE USE THEREOF

The invention relates to fluoranthene derivatives of general formula (I). Said invention also relates to a method for producing and using the inventive fluoranthene derivatives in the form of emitting molecules in organic light-emitting diodes (OLEDs), a light emitting layer containing the inventive fluoranthene derivatives in the form of emitting molecules, an OLED containing said inventive light emitting layer and devices containing the inventive OLED.

Novel perylene chromophores obtained by a facile oxidative cyclodehydrogenation route

New perylene chromophores, phenyl-substituted diindeno[1,2,3-cd: 1′,2′,3′-lm]perylenes 5a,b and 4,4′,7,7′-tetraphenyldiacenaphtho[1,2- k:1′,2′,k′]diindeno[1,2,3-cd:1′,2′,3′- me]perylenes 22a,b, have been synthesized from substituted fluoranthene derivatives 3 a,b and 4 a,b by means of a surprisingly simple oxidative cyclodehydrogenation reaction. The resulting chromophores, when substituted with alkyl chains at the periphery, show good solubility in organic solvents, and a full characterization of the novel red, green, and blue dyes by field-desorption mass spectrometry, UV/Vis and 1H and 13C NMR spectroscopy becomes possible.

Reaction of 1,8-Bis(phenylethynyl)naphthalene with Phenylchlorocarbene: Formation of an Intermolecular Cyclization Product from Carbene Monoadduct and of 1,8-Naphthylenebis(diphenylcyclopropenylium) Dication from the Bisadduct

The reactions of 1,8-bis(phenylethynyl)naphthalene (4) with phenylchloro- and dichlorocarbenes and chemistry of the obtained products have been studied.The reaction of 4 with 1 equiv of phenylchlorocarbene exclusively affords spirocyclopropene 8, whose st

Polycyclic Aromatic Compounds: Part IX - A New Synthesis of Highly Arylated Fluoranthene Derivatives

A new series of highly substituted fluoranthene derivatives (VIII), (XII) and (XIV) have been synthesised.The synthesis involves Diels-Alder cycloaddition of cyclopentadienones (I, II, III) to acenaphthylene.The carbonyl-bridged adducts (IV, IX) are cleav
