The objective of this review is to give an overview of the synthetic methods to prepare different indolo [3,2-b]carbazoles and similar systems with a potential use in electro-optical devices such as OLEDs (organic light emitting diode), OPVs (organic photovoltaic) and OFETs (organic field effect transistor). Positional selectivity and the possible role of relative stabilities of onium states of the ring heteroatoms. To explain the noncorrespondence in the series of substrate and positional selectivities in electrophilic substitution reactions of five-membered heterocycles with one heteroatom, a hypothesis was put forward ( 79MI2, 80KGS1587 ).Other names: 1H-Indole; Ketole; 1-Azaindene; 1-Benzazole; 2,3-Benzopyrrole; Benzopyrrole; Indol; 1-H-indol Permanent link for this species.

Aug 18, 2003 · For benzopyrrole, the NICS values are −11.9 and −9.2 for benzene and pyrrole, respectively. For isobenzopyrrole the values are −15.7 and −6.1 for the benzene and pyrrole rings, respectively. Both rings of benzopyrrole are aromatic, whereas for isobenzopyrrole, the benzene ring is aromatic but the pyrrole one is almost non-aromatic.
