Conducting polyheterocycle composites based on porous hosts
Journal of Electronic Materials, 1992 Conducting composites based on porous substrates (cotton fiber, non-woven polypropylene mat and porous crosslinked polystyrene) have been prepared by a two step imbibition technique. First, the substrate was imbibed with a solution of monomer (pyrrole or bithiophene) in acetonitrile, followed by partial drying.

Pd(II)-Catalyzed [4 + 2] Heterocyclization Sequence for Polyheterocycle Generation [PDF]
Organic Letters, 2018 A new Pd(II)-catalyzed cascade sequence for the formation of polyheterocycles, from simple starting materials, is reported. The sequence is applicable to both indole and pyrrole substrates, and a range of substituents are tolerated.

Fused-Ring Oxazolopyrrolopyridopyrimidine Systems with Gram-Negative Activity
Antibiotics, 2017 Fused polyheterocyclic derivatives are available by annulation of a tetramate scaffold, and been shown to have antibacterial activity against a Gram-negative, but not a Gram-positive, bacterial strain.

Copper-Catalyzed Modular Assembly of Polyheterocycles [PDF]
The Journal of Organic Chemistry, 2020 Easy operation, readily accessible starting materials, and short syntheses of the privileged scaffold indeno[1,2-c]isoquinolinone were achieved by an multicomponent reaction (MCR)-based protocol via an ammonia-Ugi-four component reaction (4CR)/copper-catalyzed annulation sequence.
