Aggregation-Induced Emission and Applications of Aryl-Substituted Pyrrole Derivatives

A One-Pot Construction of Halogenated Trifluoromethylated Pyrroles through NXS (X = Br, I) Triggered Cascade

“…Further Suzuki–Miyaura coupling with (4-methoxyphenyl)­boronic acid offers trifluomethylated triaryl substituted pyrrole 13 in 55% isolated yield. It is well-known that polyaryl substituted pyrroles show the unique optical and electronic property . Indeed, pyrrole 13 exhibited aggregation-induced emission (AIE) behavior in a solution of water-MeOH when the concentration was increased (Figure ).…”

Acid-Promoted Cross-Dehydrative Aromatization for the Synthesis of Tetraaryl-Substituted Pyrroles

“…Pyrroles are one of the most frequently appearing five-membered rings in many important molecules . Recently, with the development of electroluminescent materials, some tetraarylpyrroles were discovered to have remarkable fluorescence, which shows potential application in organic electronic devices . However, until now, most of the reported synthetic methods could only selectively afford symmetric tetraaryl-substituted pyrroles, which restrict further application of those types of molecules in materials chemistry. , In 1938, Davidson successfully prepared a symmetric tetraphenylpyrrole from benzoin .…”

3-Trifluoromethyl Pyrrole Synthesis Based on β-CF3-1,3-Enynamides

“…Subsequent Suzuki–Miyaura coupling of 10 with (4-methoxyphenyl)-boronic acid using PdCl 2 (AmPhos) 2 as catalyst afforded the triaryl-pyrrole 11 in excellent isolated yield. It is well-known that polyaryl pyrroles exhibit unique optical and electronic properties . Indeed, pyrrole 11 exhibited aggregation-induced emission (AIE) behavior in an aqueous MeOH solution when the concentration was increased (Figure ).…”
