Enhancement of the thermoelectric property of nanostructured polyaniline/carbon nanotube composites by introducing pyrrole unit onto polyaniline backbone via a sustainable method

Chemical Engineering Journal, 2019
The electrical conductivity of conducting polymer depends strongly on the alignment of the polymer chains, and a fully aligned polymer backbone strongly enhances the conjugation.

Pyrrole: An insight into recent pharmacological advances with structure activity relationship.

European journal of medicinal chemistry, 2018
Pyrrole is a heterocyclic ring template with multiple pharmacophores that provides a way for the generation of library of enormous lead molecules. Owing to its vast pharmacological profile, pyrrole and its analogues have drawn much attention of the ...

Pyrrole-Hemoglobin Adducts, a More Feasible Potential Biomarker of Pyrrolizidine Alkaloid Exposure.

Chemical Research in Toxicology, 2019
Pyrrolizidine alkaloids (PAs) are naturally occurring phytotoxins widely distributed in about 3% of flowering plants. The formation of PA-derived pyrrole-protein adducts is considered as a primary trigger initiating PA-induced hepatotoxicity. The present

Pyrrolic Photosensitizers

Current Medicinal Chemistry, 1996
Abstract: There are three major classes of photosensitizers which can initiate a phototoxic effect to tissues upon irradiation. These are the cationic dyes (Type I Photosensitizer), the psoralens (Type I and II Photosensitizer), and cyclic polypyrrolic compounds (Type II Photosensitizer).

The Hantzsch Pyrrole Synthesis: Non-conventional Variations and Applications of a Neglected Classical Reaction

Synthesis, 2018
Pyrrole is one of the most important one-ring heterocycles because of its widespread presence in natural products and unnatural bioactive compounds and drugs in clinical use.

The Dual-State Luminescent Mechanism of 2,3,4,5-Tetraphenyl-1H-pyrrole.

Chemistry, 2018
2,3,4,5-Tetraphenyl-1H-pyrrole (TePP) was synthesized by a simple one-step reaction. The compound showed a balanced emission in both the solution and solid state with the absolute quantum yield of ΦF/THF =65.6 % and ΦF/solid =74.3 %, respectively ...

The Synthesis of 3-Substituted Pyrroles from Pyrrole

Synthesis, 1985
La reaction d'electrophiles avec le pyrrole se fait preferentiellement en position 1 ou 2; pour obtenir des derives substitues en 3, on protege d'abord la position 1 ou 2 par des substituants orientant la reaction en position 3 ou on utilise en position 2 des substituants permettant un rearrangement conduisant aux pyrroles substituees en 3; une etape ...
