Usage

General Description

7,12-diphenylbenzo[k]fluoranthene is a polycyclic aromatic hydrocarbon that is formed by the combustion of organic materials and is present in air, water, and soil as a byproduct of industrial processes. It is considered an environmental pollutant and a potential human carcinogen due to its ability to cause DNA damage and mutations. Additionally, it has been linked to respiratory irritation and has been found to bioaccumulate in aquatic organisms. The chemical compound is also known to have endocrine-disrupting effects, potentially leading to reproductive and developmental issues in humans and other animals. Its presence in the environment has raised concerns about its potential health risks and it is subject to regulation and monitoring in various countries to mitigate its impact on human and environmental health.

Non-doped active layer, benzo[k]fluoranthene-based linear acenes, for deep blue- to green-emissive organic light-emitting diodes

This work studies a series of fluorescent materials, benzo[k]fluoranthene- based linear acenes, and uses these materials directly as the non-doped active layer to fabricate deep blue- to green-emissive organic light emitting diodes (OLEDs). Experimental results indicate that benzo[k]fluoranthene-based linear acenes with different substituents in pristine films have a wide range and strong intensity of the luminescence spectra. The substituents of benzo[k]fluoranthene derivatives modulate the lifetime of the excited state and PL spectra of excitonic, excimer or both emissions in the solid state. Controls of emission spectra are exploited in fabricating high-performance non-doped deep blue to green OLEDs with electroluminescence in the deep blue region (420-460 nm), green region (480-580 nm) or both (430-580 nm).

Rhodium-Catalyzed [2+1+2+1] Cycloaddition of Benzoic Acids with Diynes through Decarboxylation and C≡C Triple Bond Cleavage

It has been established that an electron-deficient cyclopentadienyl rhodium(III) (CpERhIII) complex catalyzes the oxidative and decarboxylative [2+1+2+1] cycloaddition of benzoic acids with diynes through C≡C triple bond cleavage, leading to fused naphthalenes. This cyclotrimerization is initiated by directed ortho C?H bond cleavage of a benzoic acid, and the subsequent regioselective alkyne insertion and decarboxylation produce a five-membered rhodacycle. The electron-deficient nature of the CpERhIII complex promotes reductive elimination giving a cyclobutadiene–rhodium(I) complex rather than the second intermolecular alkyne insertion. The oxidative addition of the thus generated cyclobutadiene to rhodium(I) (formal C≡C triple bond cleavage) followed by the second intramolecular alkyne insertion and reductive elimination give the corresponding [2+1+2+1] cycloaddition product. The synthetic utility of the present [2+1+2+1] cycloaddition was demonstrated in the facile synthesis of a donor–acceptor [5]helicene and a hemi-hexabenzocoronene by a combination with the chemoselective Scholl reaction.
