Functional block-like structures from electroactive tetra(aniline) oligomers

Recent advances in the fast-growing area of block-like structures based on electroactive oligomers, with a particular focus on tetra(aniline)-based structures, are discussed in this review. We provide an overview of recent literature covering aspects of design of novel molecular architectures, synthetic strategies and theoretical investigations. Specifically, we discuss tetra(aniline)s (TANI), di- and tri-block architectures before providing details of recent computational studies. We highlight useful synthetic routes, advantages of utilising block-like structures, as well as opportunities for further exploration on both the synthetic and computational fronts.
