Eaton's reagent assisted aromatic C-C coupling of carbazoles for optoelectronic applications

An Eaton's reagent assisted C(sp2)-C(sp2) coupling via the Scholl reaction mechanism was developed to prepare bicarbazoles without using any solvents and catalysts. The resulting biaryl exhibits unique optoelectronic properties as a promising host material of blue phosphorescent organic light emitting diodes, achieving high current efficiency up to 31.7 cd A-1 with ultralow roll-off.

Oxidative Coupling of Carbazoles: A Substituent-Governed Regioselectivity Profile

Oxidative C-C coupling of carbazoles possessing various substituents is demonstrated in the presence of organic (metal-free) recyclable oxidants, such as DDQ or CA/H+, for accessing bicarbazole regioisomers. Differently substituted carbazoles are examined to showcase regioselective discrimination (3,3′-versus 1,3′-bicarbazoles) and preferences based on sterics and electronics in oxidative coupling. Finally, a mechanism that involves the carbazole radical cation has been traced (evidenced) and proposed on the basis of the UV-vis-NIR absorption and EPR spectroscopy results. This study underlines the strategic chemical preparation of a series of bicarbazoles in an efficient manner.
